@@dariobarisic3502i do agree that this probably wasn’t made by an expert but do you really think a twelve year old made a deep fake about taylor series in calculus
@@hirandompeopled4968 Well, a 12 yo can for sure make a deep fake of this quality. But no, I don't literally think that this was done by a 12 yo considering it's about calculus. It was more like a hyperboly.
One thing the video got wrong: if you infinitely continue the Taylor series it won’t become e^x. The left side limit of e^x is obviously zero,and the left side limit of the Taylor series is indeterminate. Also after x amount of terms the Taylor series can no longer follow its function.
@@tiziocaio101 no, it doesn’t. There is a limit to how precise the Taylor series can become. There are several ways to prove this, but one obvious one is stated in my comment above. Top answer here covers a good bit about limits and Taylor series and polynomials.
@@joshualee1595 As far as i know it does converge to the actual funcion, thats why e^x is called an analytic function. The difference between de Taylor polynomial and the actual function tends to zero as the degree of the series tends to infinity. Tell me if im wrong, but im quite sure i got it proved using the Lagrange remainder.
I want to add something : if adding an infinite number of terms allows to fully recreate the exponential everywhere (for all real numbers and even complex numbers) it is NOT the case for every function. If the function is "cool" enough (ie differentiable a bunch of times), you will be able to approximate it very well at a certain point or even on a interval but not necessarily everywhere it is defined. Take for example ln(1+x). If you consider its "infinite" taylor expansion around 0 it will actually be valid on ]-1,1[ but not for all x > -1.
The ratio test can be used for determining the radius/interval of convergence of the general power series representation of the Taylor series; if the radius of convergence is infinity, then the original function is exactly equal to the infinite series and not just the best local approximation. :)
i NEVER understood why each term in the taylor series/any series in general “makes up” the function we’re modeling until the last 10 seconds of this video. like genuinely.
It’s setting the initial value at a point a to be the same as the target function. Then the value of the first derivative is equated to the target function. Then the second, the third, and so on. All the derivatives of a function completely determine what the future values will be. So once all the values of the derivatives of the Taylor series match up with the target function at a point, you will know that the two functions are equal. Well, except if the target function is discontinuous with any derivative.
The “why” of calculus and this is explained (through a rigorous proof) in a more advanced class called “Real analysis” usually taught in 2nd year of a math degree in college. But u can see it kind of holds true through the visualisation. again the actual full mathematical proof though requires a course in real analysis.
@@onlocklearning I'm so glad that you answered me, right away. Otherwise, assuming your video format, I would have to wait until a Pop Star by the name of Maclaurin came along.
Was just about to ask this. I haven’t learnt about the Taylor series yet ,but did see a resemblance to a maclaurin series so I was wondering if it was a different name or something.
@@B3N_J1 Calculus textbooks usually have two separate sub-chapters (one for Maclaurin series; another for Taylor series.) If you are interested, it was actually a student of Gauss, specifically Riemann, who discovered the Taylor series. In my opinion, if we insist upon naming 50 or so significant math-methods after only one guy, then it makes it really hard for subsequent students to remember each distinct math-method. So, by all means, continue to name significant math discoveries after other people (who were not the actual discoverer.)
If anyone is still confused about how it actually works, you’re equating the all the derivatives of the Taylor series with those of the target function when x=a. Ie the values of each function are set to match at x=a. then the first derivatives are the same for each function at x=a. Same for second derivative and the third, and so on, until the last term in the Taylor series is reached. This is why functions with vertical asymptotes or discontinuities tend to not able to be approximated by a Taylor series for every value of x. The derivatives stop being able to completely determine the value of the function beyond the discontinuity.
Really cute! I see you've done several of these, and I think it's a great idea. I especially think it will grab people's attention to get them to work through it their own heads, which is what's required for comprehension.
"Eventually we will end up fully recreating e^x" Ehm actually 🤓 taylor serie APPROXIMATE the original function, meaning if you keep going on forever, you will keep getting closer and closer to the original function, but you will never get end up recreating it, as by definition you can't reach infinity One simply does not reach infinity, because the moment you reach it, it means you can add one and infinity isn't the biggest value anymore. Also i need to correct myself: infinity is not a number! It's just a concept!
The precise statement is captured by limits. Let S(N) be the partially summed Taylor series, i.e the sum of the first N terms. In the limit that N goes to infinity S(N) will tend to the function. Effectively what this means is that you can always compute |f(x) - S(N)|, and that you can always make this difference smaller by making N larger.
as a math major litteraly everything is crystal clear and its fucking brainrot, I am in admiration Only thing id say is that you shouldve explained that 99% of time we stop at X order but its so awesome I love it
Can you also explain what it used for in real life. like what does it do ? I really wanted to understand math but I don't know what a certain diagram can do or represent in real life.
Well, for example you can't tell what sin(x) is equal to without using a calculator. Using a Taylor series, you can approximate what sin(x) is equal to with some good precision. In fact, Taylor series is what calculators use behind the curtain to tell you what sin(x) is equal to.
Taylor series can be used to calculate functions like e^x, sinx or any other nice function. You can also use it to prove stuff like e^ix = cosx + isinx. Sometimes its easier in physics or engineering to work with taylor series than the original function. And you can use it to show that for small angles sinx ≈ x, which is a really useful and important approximation in physics and engineering
It works, it makes you pay attention to see if the AI actually got everything right, the lip movement and the sound and meaning of what they are saying. Not kidding, this is incredible
Thank you so much for your educational video which made me realise that I do not fully comprehend maths! You indeed have a concrete understanding of them.
I just wanted to say I took the Taylor (and MacLaurin) series in a 50-minute class, yet you simplified it much easier. I definitely thought of Taylor Swift too, when reading the name 😂.
Basically you have a function f(x) which can be expressed in form of x the pattern for each term will that the term(x) with nth power will be multiplied to nth derivative of f(x) where you need to put rhe value ,and the term will be divided by n factorial
That's just Taylor's series for a=0. There's many stuff like limited form of one is given other name. Taylor => Maclaurin Laplace => Poisson Stokes => Green
I am so happy knowing that Elon is adding all those terms, forever, on some stage in front of an audience that are sure they paid to hear something else.

Honestly, if Taylor Swift were ACTUALLY to explain the Taylor-series, that would be pretty wild
Its also very interesting to note that the graph looks like a thread sewing a cloth which is what tailors do so the name tylor series is perfect
This feels just like scrolling through an electronic copy of a school textbook instead of tiktok, pupils dilated.
