Near the end of the lesson, one of my students asks a question about why the values start turning around 0.4 - I made a couple of videos that explain this phenomenon: • A Turning Point Myster... (Part 1) and • A Turning Point Myster... (Part 2)

These students don’t realize how lucky they are to have such an effective and passionate teacher. Really makes all the difference in the world to keep the students engaged whilst educating them.
2:10 That really made me sad. The way that student said "what".
Well obviously the student wasn't engaged.
Absolutely. I watch a lot of maths related videos on KZhead because I find the subject fascinating, but watching this is the first time I've actually thought about getting back into learning it formally. One bad teacher can destroy a student's interest for years - as unfortunately happened to me - but one good teacher can turn it around and this guy is great. If he'd been my teacher, I'd have a maths degree right now.
Why?
Very few teachers will have the kind of enthusiasm to show students all the great tips and techniques in any subject. Most probably are just biting their fingers waiting for their paycheck to come every month 🤔
"0 to the power of are you paying attention?" mate that was brilliant
Rudy Julian it would be approaching one since he was giving 0 attention.
I love it when this guy taps his chin and goes "hmm... what should I call this?"
and then you hear..........umm... what LOL
"wut"
Timestamp pls.
"Now that's a good question and I don't have an answer to that.... So maybe we could find out...." We need MORE teachers willing to say this.
Of course there is an answer to that question ! It's called a "local minimum" of a function
@@solcarzemog5232 Correct. In this case it is a switch between the predominance of the the value towards its factor. Then you wonder why you deposit zero dollar to the power of zero in your bank, and the stupid clerk does not give you dollar. Could take time to convince him.
as a math major I'm not satisfied with this answer. There are many things where the limit does not equal the value. It could have been the answer that the limit was 1 but the true value was undefined or possibly 0 but maybe it can't be that I forget. After looking it up, it says that this is a very rare case where it depends on the context. For us viewers, it would have been nice it they went over that because this gives us the false impression that the value always equals the limit.
@@bztube888 what? how is it a minimum? what do you mean? I have a math degree
The x^x function's minimum at x=1/e (about 0.3679). Of course it's something e. But that's for another lecture so he gave the perfect answer.
I really like his teaching style. He's very engaging and honest enough to say "I don't know, but I can find out." My understanding of maths is too basic to really appreciate the lesson though.
You're probably not as far away from understanding as you think. The equations on the board at the start are just giving you the notation, The top line is telling you that 'this is short form for that'. a^m = a times a times a times a, m number of times. Next line I will just give an example if a = 2 and m = 3 and n = 2, that means (a^m) x (a^n) = (2x2x2) x (2x2) which equals 2^5 = a^(m+n). I don't know if that helps, maybe, maybe that wasn't even something you were stuck on haha. But don't give up on understanding if you want to get better at math, I always found the "That looks too complicated" feeling to be my worst enemy when learning it.
Here he’s laying the baseline for the fundamental theorem of calculus, which is where maths takes off.
@@HouseTre007 Thanks for the reply. Now I shall have to look up what 'calculus ' means because I didn't learn about that in school.
@@localbod maybe in your curriculum it was called Math analysis or pre math analysis
@zerere I moved around a lot as a kid, roughly every two years. I never got my head around basic maths, and because my level was poor, I got put into a class with all the dropouts. It is interesting, though, and he is a good teacher.
I love how he literally stopped his whole class for the sake of the one kid who had stopped paying attention, and the kid who told him to get off his phone sounded legitimately angry. I feel like this guy has succeeded as a teacher because of the fact that he has his students so engaged and he cares enough about the individual to stop the class to allow them to regain their focus. These are the teachers we need more of. Its always refreshing to see a teacher who genuinely cares and also tries to make learning fun, while at the same time trying to make the content he gives to his students more easily understood. He simplifies things as much as possible in order to benefit everyone in his class, and I think that deserves tons of respect.
Hi Dimitri, interested in math competitions? If so, take a look at kzhead.info/sun/pc-zqMiFfXd7p68/bejne.html and others in the Olympiad playlist. You will see a lot of tricky and somewhat complex problems to try. Hope to see you there.
If you want excellent teachers, you need to completely revamp the system. The current system makes teachers overworked, underpaid, and burnt out.
Some of my teachers were like this too, some of them...not so much. If you pay teachers well and give them good working conditions you'll probably get better teachers. I have no idea how it is in Australia though (where this guy is from).
I love how he stopped the class for that one unfocused kid. Teachers who are passionate, kind, caring and engaging sometimes can be disrespected by students because he is, well, too nice. That's just how teenagers function sometimes, no judgements. Stopping the class and politely ask for attention can serve as a hint or "warning" to the students that while the teacher is kind and caring, he has standards and is to be respected. He then smoothly moves on without making the student too uncomfortable and impacting the flow of the class. This makes me think not only is he great at teaching, but also understands how students think and respects that.
That sounded like a girl to me.
13:56 For anyone wondering why this number starts increasing again specifically between .4 and .3, it's because the minimum value of x^x (x to the x) happens at x = 1/e, aka. the inverse of Euler's number, aka. ~.36788, which, as you would notice, is between .4 and .3. You're welcome.
Gratias, Amigo. I'd like to see a graph of the relationship of x and x raised to the power of x
It happens because of witch craft!
@@joemarshall4226 Follow the spirt of the lesson and plot it for yourself ! Normal exponential behaviour i.e rapidly rising curve above x=1, then a v shape between x=0 and x=1. For x < -1, a flat curve that gradually rises from -1 towards 0 as x gets increasingly negative. The bit between x=0 and x = -1 is left as an exercise for the reader.
@@jonathansmith2734 hi the devil sent me.... he loves your work
Yes, you're absolutely right. I noticed this before I read any of these comments. As I started watching this video, I generated a list of decreasing numbers by using MS Excel. In column A, I made a list of the positive integers in increasing order. I made each entry in column B to be the reciprocal of the corresponding entry in column A, and each entry in column C to be the value in column B (of the same row) raised to the power of itself. Seeing that the value in column C was indeed the same for the 2nd row and the 4th row, i.e., (1/2)^(1/2) = (1/4)^(1/4) = 1/sqrt(2) = half of the square root of 2 (which I already knew it would be), I created 9 rows between 2 and 3, and put in column A 2.1 through 2.9, and carried the equations for columns B and C into the corresponding rows; then, seeing the results in column C, I inserted 9 rows between 2.7 and 2.8 and placed 2.71 through 2.79 in column A, and repeated the process for the new rows in columns B and C; then, seeing the results in column C, I inserted 9 rows between 2.71 and 2.72, and placed (in column A) 2.711 through 2.719, and finished that step with the corresponding entries for columns B and C. It was here that I got the idea that the number in column A that produced the smallest value in column C might be Euler's Constant (e). I continued this process until I had the smallest value in column C when the value in column A was 2.7182818. But then I computed the first derivative of x^x = (x^x)(1 + lnx), and setting this equal to zero, 1 + lnx = 0 and lnx = -1 and so x = e^(-1). So, yes, the minimum value for the function f(x) = x^x is found when x = (1/e). And yes, the limit of x^x as x approaches zero is 1.

@@prototropo yeah and the best part was he didn't punish the student for not listening. That would completely ruin the spirit of learning. It's often saddening to see that someone who either doesn't understand or loses attention is punished thus making them act like they are listening just to not have to deal with the punishment and thus end up hating the subject and the teacher. Do this with multiple teachers and ultimately they're hating school.
As a Maths teacher as well, I must confess that this guy is really good. Choosing the right words and keeping the students engaged.

I love this energy while teaching. You convey the subject really good and keep the students interested and it really sticks.
0^0 is an interesting one in that math textbooks and math teachers will usually insist that it's undefined (because if you take x^y, what you get in the limit x,y -> 0 depends on what path you take through the x-y space), but professionals in most contexts just take it to be 1. If you think about it, every time you write a polynomial or power series using a summation notation over powers, you're implicitly assuming that x^0 = 1 for all x; otherwise you'd need to include a special case for x=0 every time you did this.
Great comment! I also want to add a bit of a historical note. In the 1700s, pretty much every mathematician accepted 0^0 = 1 as true. So how did we go from 0^0 = 1 is true to so many people shouting that 0^0 is undefined? It's because of the switch from infinitesimals to limits. In the late 1700s and throughout the 1800s, mathematicians were becoming wary of the way infinitesimals were used in Calculus. In the early 1800s, Augustin-Louis Cauchy introduced the notion of the limit of a function as the input approaches a certain value. So instead of plugging in infinitely small values, they could now take the limit as the input tends to 0. Cauchy also included a list of indeterminate forms. This list of indeterminate forms included 0^0, and Cauchy was right to include it. 0^0 really is an indeterminate limiting form. This caused the mathematical community to have a bit of a panic concerning the arithmetical value of 0^0 because 0^0 was an indeterminate limiting form, so they un-defined 0^0. No longer was it considered 1; it was now undefined. But this panicked move was not based on sound reasoning. 0^0 being an indeterminate limiting form means that if f(x) approaches 0 and g(x) approaches 0, then knowing this information is insufficient to tell what f(x)^g(x) approaches. The limit of f(x)^g(x) could, conceivably, be any nonnegative real number, positive infinity, or not exist. But the important thing about limits is that *_limits do not have to agree with the function value._* The limit of f(x) as x approaches c could be different from f(c) itself. So just because 0^0 is an indeterminate limiting form does not imply that 0^0 must be undefined as an arithmetical operation. With more development into discrete mathematics, abstract algebra, universal algebra, set theory, and category theory, we know now that 0^0 = 1 will *always be correct* in the context of discrete exponentiation. What I mean by this is the following: if you ever have a formula involving exponents where the exponents represent repeated multiplication, if you can get 0^0 from that formula, the formula will give the right answer (for what the formula is supposed to represent) if and only if 0^0 is evaluated as 1. It's not an accident. It's not a happy coincidence. There's a perfectly reasonable mathematical idea which shows us why this will always work (the empty product). But unfortunately, the mistaken reasoning from the 1800s is still perpetuated to this day.
@@MuffinsAPlenty _"if you ever have a formula involving exponents where the exponents represent repeated multiplication"_ Isn't that equivalent to saying "the exponent is a non-negative integer"? Well sure, if we're only going to deal with non-negative values of x, then we only need consider the limit as x tends to 0 of x^x coming from above, and that's well-behaved and equal to one. But what about the cases where the exponents _aren't_ all positive integers? Then the value of 0^0 doesn't exist, so perhaps the reasoning from the 1800s was sensible after all?
@@RexxSchneider Why would you say that 0^0 in the context of discrete exponentiation should match up with lim(x→0+) x^x? Why not match it up with lim(x→0+) x^0? Why not match it up with lim(x→0+) 0^x? Why not match it up with lim(x→0+) x^(-1/ln(x))? The issue in the 19th century reasoning is pretty much a categorical error. It's saying that f(c) can't be 1 because lim(x→c) f(x) isn't 1. It's a fundamental misunderstanding of what limits mean and what their purpose is. The definition of "lim(x→c) f(x)" intentionally ignores f(c). Arithmetic is different from limits. It would be, in no way, a contradiction for 0^0 = 1 to be true while lim(x→0+) 0^x = 0 is also true. All this means is that 0^x is not continuous from the right at x = 0. Here's another example for you. Let ⌊x⌋ denote the greatest integer less than or equal to x, when x is a real number. By definition, ⌊0⌋ is the greatest integer less than or equal to 0, so ⌊0⌋ = 0. On the other hand, you could consider things like lim(x→0) ⌊x⌋, which doesn't exist, lim(x→0) ⌊x^2⌋ = 0, or lim(x→0) ⌊-x^2⌋ = -1 From this perspective, we could say that ⌊0⌋ is an indeterminate form. If you have a limit, and evaluating the function at the point in question gives ⌊0⌋, this is not enough information to determine the value of the limit. No one in their right mind would use this justification to say that ⌊0⌋ must be undefined. But that's the reasoning that 19th century mathematicians used to un-define 0^0. Just because not every limit gives 1 when you approach 0^0 doesn't mean that 0^0 itself must be undefined. Now, you could get into discussions about how when we move from rational number exponents to real number exponents, we need to use some analytic tools in order to define exponentiation. And sure, depending on what your definition of exponentiation is, 0^0 is probably undefined. (But also, depending on what your definition of exponentiation is, your definition of 0^2 might also be undefined. For example, z^w = exp(w*log(z)) leaves all powers of 0, including things as simple as 0^2, undefined.) Additionally, in pretty much every situation, analytic exponentiation is an extension of discrete exponentiation. For example, if you go the exp(w*log(z)) route, you typically would define exp(x) as a power series, which involves discrete exponentiation of x. So you are building up from the definition where 0^0 = 1 is the only way to go. To make things clear, if you want to study continuous functions, un-define 0^0 in that context. It's a good choice in that one specific context. But it shouldn't be seen as the correct thing to do generally. We shouldn't view 0^0 as actually undefined, except in any practical application, where 0^0 is defined as 1 for convenience; rather, we should see 0^0 = 1 except in the one instance where it's convenient to un-define 0^0. I would also argue that the 19th century reasoning causes problems with students understanding indeterminate forms in general. Particularly things like 1^∞. A lot of students will be very confused about 1^∞ being an indeterminate form. They will view 1^∞ as 1*1*1*..., and they can't see how 1*1*1*... can possibly have any value other than 1. And there's something to their confusion. In any context where 1^∞ can be viewed as actual arithmetic, either as 1*1*1*... or as 1^α where α is a transfinite number (e.g., cardinal number, ordinal number, hyperreal number, surreal number), the value is always 1. *_But_* if f(x)→1 and g(x)→∞, this isn't enough to tell us what f(x)^g(x) approaches. And that's because limits are not the same thing as arithmetic. I think a nice way to see my point is to try defining "indeterminate form" without simply writing a list of indeterminate forms.
@@MuffinsAPlenty Thanks for the wall of text. Did you read what I wrote? I'm pretty certain that I stated quite clearly "if we're only going to deal with non-negative values of x, then we only need consider the limit as x tends to 0 of x^x coming from above, and that's well-behaved and equal to one." Then you proceed to spend reams of text arguing that if we only deal with non-negative values of x, we can define the value of 0^0 to be 1. *I already said that was the case.* Anyway, the reason we don't take f(x)=x^0 or f(x)=0^x is that those give differing values as x tends to zero, so they are not the function we're dealing with, which is f(x) = x^x. You tell me that "Just because not every limit gives 1 when you approach 0^0 doesn't mean that 0^0 itself must be undefined." But that's exactly what an indeterminate form is. The problem is not that we don't define 0^0, it's that the process of taking a limit isn't leading us to an unambiguous value. Surely you understand the difference? 1/0 is undefined, but 0/0 is indeterminate. The 19th century reasoning is comes about because they actually understood limits, and defined a limit as applying to functions that are continuous in the region containing the limit, which x^x is not in the neighbourhood of x=0. The whole point of having a limit to stand in place of f(c) when f(c) is arithmetically indeterminate is that it preserves the continuity of f(x) when x passes through the region containing c. When x is discontinuous in that region, then you can't use a limit. Yes, of course, you can choose to assign the value 1 to 0^0 when x is a non-negative integer, because x^x is a continuous function for x>0, but that's just a choice made for convenience; there's nothing fundamental that requires 0^0 to take on that value. I understand you take the opposite viewpoint, and assert that 0^0 has the value 1, except when we choose to call it undefined. I do view 0^0 as undefined, except for those cases where it is convenient to treat it as 1, and I maintain that the latter is an artificial choice.
@@RexxSchneider I think you _might_ under the impression that the definition of discrete exponentiation doesn't assign a value to 0^0. And if you have that impression, I understand why you would view 0^0 = 1 as artificial. After all, we have the original definition, then we extend using algebra, and then we extend using analysis. Now, if you believe that 0^0 isn't defined, then using algebra to extend the definition of exponentiation won't pin down a unique value of 0^0 (this is probably what you mean by "arithmetically indeterminate"). And using analysis to extend the definition of exponentiation won't pin down a unique value of 0^0 either (because 0^0 is an indeterminate limiting form). And if it were the case that the original definition didn't assign a value to 0^0, I would agree that this is compelling enough reason to declare 0^0 not defined and all places where 0^0 is replaced with 1 to be artificial context-dependent patches. But the original definition of exponentiation as repeated multiplication _does_ assign a value to 0^0. For a nonnegative integer n, x^n is the product with n factors where each factor is x. In the case that n = 0, we have the product with no factors (each factor being x is vacuously true). This is known as the empty product, and it has a value of 1. Now, the empty product is a choice, and you may consider this to be artificial. However, what I consider to be important here is the reason that we assign the value of 1 to the empty product. And that's because, if we expect the empty product to be consistent with the generalized associative property of multiplication, it _must_ have a value of 1. If we assigned the empty product any value other than 1, the generalized associative property of multiplication would be false when empty products were involved. Knowing this, 0^0 is the empty product, and thus, has a value of 1, right from the definition of exponentiation as repeated multiplication. Now, the generalized associative property of multiplication is extremely important for exponentiation. It's the entire reason why exponentiation is even well-defined in the first place [is x^4 equal to ((x∙x)∙x)∙x or (x∙(x∙x))∙x or x∙((x∙x)∙x) or x∙(x∙(x∙x)) or (x∙x)∙(x∙x)? It doesn't matter because they're all the same thanks to the generalized associative property of multiplication]. The generalized associative property of multiplication is how we prove the most important property of exponentiation: x^n∙x^m = x^(n+m), which we use in pretty much every extension of the definition of exponentiation. The most important property of exponentiation is used in pretty much every formula involving discrete exponents. This is why I can have confidence to say 0^0 = 1 will always work in any context where we have discrete exponents. The reasoning that gives us 0^0 = 1 is the same reasoning that makes exponentiation well-defined in the first place and gives us the workhorse of exponentiation, which we use to extend the definition and use to develop every formula using exponentiation. From this perspective, 0^0 = 1 has the same amount of justification as 0! = 1. When we consider the empty product, 0! = 1 pops right out of the original definition of factorials. Factorials are only well-defined because of the generalized associative property of multiplication, the most important property of factorials is that (n+1)∙n! = (n+1)!, and this is proven using the generalized associative property of multiplication. Every formula involving factorials is built up with this most important property. Extending the factorial function to the Gamma or Pi function uses the most important property of factorials (since 0! = 1 can be justified using (n+1)∙n! = (n+1)! alone, the analyticity and log convexity of the Gamma/Pi functions have nothing to do with 0! = 1). And every argument used to "justify" that 0! = 1 should be true uses the generalized associative property of multiplication. I doubt you're going to be telling me that 0! is actually undefined, but 0! = 1 is an artificial patch which always works in any meaningful situation. But hey! You might tell me that. So that's the story. 0^0 = 1 falls out from the definition of exponentiation at its most basic level. When we extend the definition of exponentiation using algebra, keeping 0^0 = 1 doesn't produce any contradictions. So while algebra wouldn't be able to pin down a unique value for 0^0 if 0^0 weren't already defined, there are no issues with keeping the definition what it originally was. The same thing is also true for extending the definition of exponentiation using analysis, with one small caveat. The fact that 0^0 is an indeterminate limiting form does not contradict 0^0 being defined as an arithmetic expression (as my previous post argues). The caveat is that, depending on your definition of exponentiation using analysis, it's possible that all powers of 0 are undefined. In such a case, 0^0 would, indeed, be undefined using that definition, but so too would things like 0^1 and 0^2. This is why I say that analysts un-define 0^0. And sure, it's not a bad decision if you're dealing with continuous functions (unless you're only dealing with analytic functions, in which case you want 0^0 = 1 again). And this is perhaps why it felt like I ignored your previous post when you said "if we're only going to deal with non-negative values of x, then we only need consider the limit as x tends to 0 of x^x coming from above, and that's well-behaved and equal to one." It's because this suggestion doesn't make any sense when we're talking about discrete exponentiation. Limits don't make sense when talking about discrete exponents. And maybe you believe there isn't a discrete way to make sense of 0^0, so taking the limit of a particular function is the only way to justify a value of 0^0. But that's not correct.

I'm so happy that the student asked why it turned around, because upon seeing what you were doing, and after plugging the problem into desmos, I worked out that because anything to the power of a fraction is basically just taking the root of that number, and the square root of a number less than one will get larger, therefore eventually there is a threshold where the number gains more from the root than it loses from the base.

@@SUBSCRIBENOW123. going to the end of grad school is almost 200 teachers already, then you add other types of teachers like at jobs and hobby classes
@@SUBSCRIBENOW123. I'm 31, I can say I had about 100 teachers. I dont really remember how many subjects I had in middle school, it was a lot, the number 9 pops into my head. I remember I had pretty much the same teachers from grades 1 through 4, then a whole new roster from 5 to 8 (my country's ed system has 8 years of middle school, then 3 years high school, then college, btw) then I went to a new school for grade 1 high school, then a new school for grades 2-3... Just that already goes over 100. Then technical school (sort of middle ground between high school and college, idk what it's called in NA) I had about 12 different teachers, then college where I had way over 20 teachers... I wouldn't be surprised if I had over 200 teachers in my lifetime, so 100+ is not unbelievable. I, too, like this teacher. Very nice way to explain limits and the students seemed to get interested when the calculator part rolled in, that's a sign of a good teacher. My calculus teacher in college was great, too. He explained limits in a very different, more complicated way since he went deeper in, explaining why the increase starts between .4 and .3 (euler's number) and some other rules that I honestly dont rememebr cause I dont really use limits in my field, but he had a great way of putting things that made it easy for you to visualize stuff, and he was great with little songs/mnemonics to remember stuff for tests that I still remember to this day.

I’m 40 years now. And never thought I would spend 14 minutes on a math video. This guy is such a great teacher. Lucky who have a teacher like this.
I’m not saying anything you don’t already know, but this method of teaching is superb. Anyone can tell students that zero raised to the power of zero is equal to one. But you let the students discover it. They will never forget. When I was in grade school many(oh so many) years ago, my teacher told us to go home and measure the circumference of tin cans and the diameter and bring the results back to class. None of us knew why and none of us understood the meaning of Pi. We did the next day! Thanks so much for these lessons you post.
If only my secondary school maths teachers were as enthusiastic as Eddie. Great video.
EKGaming were*
Eddie is still young. Maybe after saying the same thing for 30 years he'll be less enthusiastic.
I'd prefer someone less enthusiastic, more concerned with finishing the course..
Same here. Some of my best math teachers were the ones that were actually excited about the subject and the concepts they were teaching at that time. Wish there were more like him.
a possible cause for maths teachers losing enthusiasm is that after, probably, doing higher level, more advanced math, going back to teach relatively basic concepts doesn’t bring any joy. it’s like secondary school students revisiting 2x3 (the general logic behind it, not the calculation specifically).
“Now that’s a good question, and i don’t have an answer to that at least i mean i dont have one right now probably because i haven’t really thought about it all that much to be honest. There’s always reasons for everything. So maybe we could find out where they go.” Things done by just these sentence: -Appreciate student for asking means appreciating them for using their logic and also appreciates their courage to voice their logic. -Being honest to what that is not known by the teacher, rather than making up answers or saying “that is just how it works”. Admitting incapabilities or mistakes in certain area will not decrease your integrity as a teacher, rather it build trust with your student and increase your integrity as a teacher. -Rather than discouraging students and teach them not to overthink things too much, he took the other way around and told “there’s always a reason for everything” then leaves the sentence ends with encouragement that we could find out about it. Good job ed
Yes I was looking for this comment! The answer I would have received was " that's just how it is ..."
It turns around at 1/e, obviously. ;-)
@@landsgevaer Huh. You know, it never before clicked in my head that e is the tipping point when adding to the exponent scales faster than adding to the base.
x^x reaches a minimum when ln(x^x) reaches a minimum. This simplifies to d/dx x*ln(x) = 0, therefore x*(1/x) + 1*ln(x) = 0, so ln(x) = -1, so x = 1/e. #

He could have just said: "it's 1 remember it, it'll be on the exam" , and continued, but he's done more: he gave them meaning, passion, curiosity, knowledge. The fact people hate Maths, or anything for that matter, it's because they learn it from the wrong people. It's because some doctors, or business men, could have been good teachers and they chose to be something else to make the money they think they deserve. I hope this teacher continues to be the same and contaminate his students with his passion.
Dihcar bahari bhai,i am convinced with what u said, In this world there is a problem of money everywhere no one does anything with passion for it they just perfect something for earning and because of obvious pressure from society ,generally they are called middle class but it can be anyone post script i know u r talking about mathematics here but what i believe about the world i said that
In this world the main problem is teachers themselves don't have full knowledge....What would they feed to their students
Don’t entirely agree, alot of doctors chose to study medicine for the soul purpose on wanting to help people. Not saying that there aren’t doctors who do it for the money, but alot of doctors, as kids, probably dreamt about helping people for a career. Regardless of the money, majority of doctors are there because they want to be.
Your totally right, I'm an engineer so naturally I have had a lot of math teachers. Some of them fantastic, some of them so so and some of them made me hate life. At one point I thought I was terrible at math but it took one good teacher to show me I actually have a good mind for it. A good teacher can be the difference between understanding and frustration. A good teacher can teach anyone regardless whether they have the mind for it or not and a bad teacher can make someone who does have a mind for it hate the subject.
He can’t because the right answer is undefined
I am over 50 and I do teach at Univ at times BUT I wish I had a teacher like him in school/univ. I watched the entire video just out of curiosity and I was amazed by the journey of learning (so to speak) he took me on. Best part was in the end when a student asks a questions and he replies that he didn't know. I am from India and the education culture largely (changing though nowadays) is not to question the teacher. This emanates from the culture of respect to elders and the highest is accorded to a teacher who is supposed to be wisest of all. But this approach is misplaced when it comes to knowledge sharing.
This showed up in my recommendations and I thought, I'll watch a little bit of this, but I ended up seeing the whole thing. I wish I had a teacher with your enthusiasm in my school years.
23 years ago I asked my maths teacher this problem. Today I get my answer.
Actually zero to the power of zero can't be defined. However, if you take the limit of x to the power of x with x approaching zero you end up with 1. Thats not to say that zero to the power of zero is exactly equal to one. The correct answer is that it can't be defined.

Yes, it is important to be honest. However, a trained mathematician should know the properties of such a simple function, it is inappropriate to say "I don't know" here. People who are not good professionals should not even teach children.

Good teaching style. Students are lucky and Eddie shows things clearly.
What a brilliant teacher who actually makes math interesting and enjoyable in my opinion. The difference between a good student and a poor one is no double influenced/determined by the teacher.
I'm experiencing being math teacher for the first time. I did just 6 months yet but it was enough to realize my own weaknesses and strengths. This guy not just only saying the right words. He uses extremely perfect tempo and intonation. He makes you believe you understand and since you believe that you already do understand. Amazing! His communication and way of explanation and confidence is perfect.
I've been a teacher for many years and I've trained and mentored many teachers. There are many many ways to be a good teacher. But here's my tips. Understand your own persona and play to your strengths. Have a clear goal and a well thought out route to that goal. Keep up the pace. Be respectful and demand respect in return. Be kind but be the boss. Enjoy leading your students down the path you've chosen. But you're absolutely right...let the students see the answer just before you "show" it to them.
His tempo is actually very fast. It is good for the lecture, but not good for the actual learning. Believing in understanding something isn't the same as actual understanding and reproducing results. And of course you need to consider the age of pupils. Speed of understanding the material isn't the same at 13yo, 15yo, 17yo or 20yo students...
One thing I like about his videos is the way he can recover from making a mistake or a poor notational choice without getting flustered or losing the trail of the argument. That is real skill.
500th like😁
I don’t think it’s about tempo and intonation. I think it’s about passion.
I love how the students in this class actually answer the teacher's questions....my class is usually dead silent with a few people murmuring the answer. I guess that's what you get for constantly telling kids to shut their mouths since early primary school.
And Im sitting here wondering why the hell everyone is talking so much.

I feel the same way dude. I'm not a professor, but I am a student (and at school 12th grade is last year), and I understand. When I was in 4th-10th grade/12, I was in a school were classes were really distracted off the subject of learning due to bad student behaviour, but I was always siding with the teacher while listening intently to the lectures. When I entered 11th grade at another school, the classes seemed to be too silent, and I was the only person shouting the math, Bio, chemistry... answers aloud(due to my passions), which was kind of disrupting at first, but because I'm clever (answer most questions correctly), I didn't receive much warning(not more then 2) last year 11th year. And now same as last year, I'm in grade 12/12th grade, and I'm still being the only speaker in class which is still weird, but I will hang on to being active in class. Proud to see professors somewhat advocating for more of this.

0^0 is 0. 0 powered by 0. K k, 0 doesn’t have an actual amount since it’s nothing. So powering nothing by nothing is nothing
Subjective Object
I was always taught that exponents include an implied "x 1". For example, 3^2 is 3 x 3 x 1. So you can think of the exponent telling you how many of the base numbers should appear, multiplied by each other and by one. If you have 3^0, that's just 1 because there are no threes to multiply together, just the number one. Likewise, if you have 0^0, you have no zeroes to multiply together, just the number one.
I was taught x^0=x/x so 0^0=0/0 but that's why say 5^0=5/5=1
Also what I think 0/0 is is that x*0==0 so since x can be anything if you isolate x by division x=0/0 so 0/0= anything

Great idea to look at limits and exploring how a calculator deals with 0^0. The other problem not explored is the mathematical idea behind zero power, namely division by zero creating something undefined. It would be interesting to consider how this sits with an answer from limit of 1. Really interesting problem in maths here. Great presentation!
