      @@remittri learning never ends, and Taylor series are a pain in the ass at university too.

    You need brackets around the r to denote the r-th derivative of f and g. The superscript on the f and the g should be (r) and not just r. The way it is currently written is given the r-th order composite of f. You have got the notations d^rf/dx^r and f^(r) mixed up.

    So I guess it would be fair to say that Taylor's series is a generalization of Maclauren's series. I guess Colin Maclauren was into Taylor's series even before Brooks Taylor "invented" the taylor series? I wonder if any of these two guys would be salty towards each other.

    At 3:35, I thought you’re replacing all xs with x+a. But you just wrote down x??

    thank you so much for this :) i was always confused between my teacher writing this in the way of the second line and the internet showing me the third line xP

    hi sir how does diffferentiating f (x+a) and then letting x=0 gives you f'(a) ?

    You say that x it 0 but you use x instead of 0 in for example f'(a)x. Why is that?

    In the expansion of f(x+a) you said to replace all x's with x+a but you didn't do this. Why?

    • @monzur1947
      @monzur1947 7 ปีที่แล้ว +2

      In the first instance, we let g(x)=f(x+a). So where ever there exists g(x) it becomes f(x+a). In the second instance, we let x=x-a, so where ever there's x, it becomes x-a

      ​@@monzur1947 let x=0 and replace x with x-a, mean the first term is f((x-a)+a) hence f(0) but, why in 5:28 f(a)?

    Misleading. Not a derivation of the Taylor series but just some simple applications.

    Do we need to prove this formula in the exam?

    several mistakes spotted, flawed logic too, the alt formula you are saying if we replace bla bla bla BUT you dont say WHERE. also by that logic in the first one you said "then we multiply by x" but on the second one you said "we multiply by x-a" but YOU NEVER SAID WHY!
