I still need help with my first Taylors expansion thread, but this is a seperate problem(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

a) Give the formula for the Taylor expansion of the function f(x) about the point x=a. You should include the formula for the coeffiecients of the expansion in terms of the derivatives of f(x)

b) Find the first three non-zero terms of the Taylor expansion about x=1 of the function

f(x)=exp(x^3-1)

2. The attempt at a solution

a)

f(x + a) = f(a) + xf'(a) + x^2f''(a)/2! + ... + x^nf^n(a)/n! ... where f^n(a) means the nth derivative of f(a)

I think I might have missed the point of this question.

b)

f(x+1) = 1 + 3x^3.e^(3x-1) + [9x^6.e^(3x-1)+6x^3.e^(3x-1)]/2

I'm assuming here that exp(x^3-1) means e^(x^3-1), but this isn't notation that's used anywhere else on the paper.
