Is it possible to gain an intuition for what it means for a function to be classified as 'analytic'? I understand what it means for a function to be infinitely differentiable. I think it means that all its higher derivatives are continuos. However, roughly speaking, what property does a function need to possess, to be Taylor expandable in addition to being smooth?

Just think of how much was left unsaid about integrals! I do intend to revisit this playlist and add videos on simple differential equations (separation of variables), how and why substitution works in figuring out tricky integrals, and integration by parts. In the immediate future, however, there are other projects I'd like to sink my teeth into. Please do keep exploring math, whether that's delving more into calculus, linear algebra, number theory, taking my sincere recommendations about 3b1b.co/aops or 3b1b.co/brilliant, or even just sitting down in a quiet room with nothing more than a pencil, paper, and a supply of curious thoughts.

I've recently been doing some random derivatives as I learned how they worked in the begining of this series, but I wanted to do it algebraically as well, because it just feels nice to see the numbers crunching and canceling to a nice formula. I was stuck on proving that e^x was its own derivative when I stumbled upon the exponential function described as an infinite series. When I realized it came from this Taylor series, my jaw just dropped in amazement as my brain tried to process all this information. It's kind of hard for me to study calculus, because I'm in 9 grade (which is middle school here where I live) and teachers don't really have time to really help me in the short period I spend in school, so the internet, specially your series, has helped me A LOT.

Thanks for your fast reply. However, I already understand that, as I stated I know what a derivative is. The thing that I don't understand is - why do you describe/express the slope as height/length ratio (dy/dx). For example - I think that the slope should be calculated via the pythagoras theorem (slope^2=length^2+height^2). Again, thanks for your time, it is much appreciated.
@DDranks7 жыл бұрын
That would be the *length* of the hypothenuse of the triangle representing the slope. But the length has nothing to do with how *acute* the slope is. You can't calculate that with Pythagoras theorem. What the word "slope" means is the angle of the hypothenuse expressed as a ratio of the tangents.

this is a good example of how much there resistance there is to doing things better. especially in education, people are slow to change bc they know it would mean they would have less work. if people could learn math at 10x the rate, then that would mean 1/10 the jobs (all other things constant), or at least thats how people see it. i think its the reason we need universal basic income- people would be able to move out of the way of innovation bc they wouldnt be so reliant on the paycheck

Walter I agree. We spend a lot of time just trying to survive. Many times I’ve thought: Here’s your mansion and your food for the rest of your life. Now do something productive for humanity!Obviously it is an exaggeration but I agree things would be better with a minimum income or guarantee for everyone. Having just the basics to survive, even if it is 10m2 and a baguette or pizza a day, would mean we could focus so much time on productive things.

But, I swear, this video completely opened my eyes about how exactly, or rather, why exactly it looks like it does. Thanks a lot for that, that was extremely helpful!!

@Another Random Cuber maybe. However, this only really becomes helpful if made clear to the students why the approximation works, and when it doesn't, so if they run into the need for more accurate approximations in their work, they know HOW to get more information, i.e. add another term. I know nobody asked but this bothered me when it was taught to me.

In AP Calculus BC, when Taylor Series were introduced, I was simply confused. It seemed as if my teacher was simply getting formulas out of thin air. I proceeded to memorize the formulas and do well in the class. But not until watching this amazing video did I really understand what was going on! The idea of approximating a function through taking many higher order derivatives at one point is simply mind blowing. After thinking about the video, I now realize the importance of the many tests for series convergence that we had to learn. Taylor polynomials are created to model functions that have real life applications in physics and engineering, and the best approximations we have are Taylor series. We need all the tests for series convergence in order to determine whether or not the Taylor series that we create will actually provide an approximation that will be accurate at a given point! If the Taylor series is divergent then it won't approximate at all, if it is conditionally convergent it will approximate only within the interval of convergence, and if it is convergent then it will approximate everywhere. Awesome stuff! And people say math isn't fun...

Ok, I really like calculus. But this video was more than epic. I actually paused when he got the aproximation for cos(x) up to x^2 and tested what happens when I add more terms. I found the sequence 1 0 -1 0 and that factorial thingy and managed to write the actual sum of this for k=0 to infinity. When he introduced the Taylor series into the video I googled it for cos(x) only to be left shocked. It was THAT easy??! Now I may become more into calculus than ever!

Jee 2018 cracker here. I was always confused about the series during my jee preparation. Teachers weren't able to answer from where these equations came and it pissed me off so much. Internet was not so prevalent then. What I did back then was to relate the kinematic equation derivation ( from HC verma ) and these series and formulated the taylor series myself. if acc is constant s = s0 + ut + 1/2 a t^2 which is simply the taylor series for displacement s = s0 + s' * t + 1/2 * s'' * t^2 This way I was also able to solve the questions including jerk ( accn non constant ) by easily writing the equations directly. Feels so good to watch you all being able to form a intuition with such great videos and not being limited by the teacher teaching you. All the best for your exams 😄
