Best ResponseYou've already chosen the best response.1the taylor series is , does it say about x = 0 ? i assume it is

Best ResponseYou've already chosen the best response.0I am assuming that x=0 too

Best ResponseYou've already chosen the best response.0I am not sure why we assume x=0 in this case but whtvr

Best ResponseYou've already chosen the best response.1sum f^(n) (a) (xa)^n / n! = f(a) + f'(a) (xa) + f '' (a) (xa)^2/2! + ...

Best ResponseYou've already chosen the best response.1we dont have to, it just makes it much cleaner

Best ResponseYou've already chosen the best response.1and by cleaner i mean simpler , since x  0 = x , instead of x  1 or x  2 , etc

Best ResponseYou've already chosen the best response.1so now lets plug in f(0) + f'(0) *x + f ' ' (0) * x^2/2 + ... , since we want just the first three terms

Best ResponseYou've already chosen the best response.1e^(2*0) + 2*e^(2*0) * x + 4*e^(2*0) *x^2/2

Best ResponseYou've already chosen the best response.1, remember a taylor series is approximating a complicated function (here exponential) with a less complicated function (polynomial)
