Thread: help with the taylor series for a bonus problem

hey all,

i am stuck on a math problem that no one i've talked to can figure out. the idea is i have to find a taylor series in x - a through the term (x - a)^3 for the problem:

2 - x + 3(x^2) - x^3 , a = -1

if anyone has ANY idea at all how this is done, please let me know. thank you.
