This is part b. of the problem. I found T_3(x) but I really don't know the process to find the estimate of accuracy of the approximation.

HEre is the problem:

a) Approximate f by a Taylor polynomial with degree n at the number a.

on

My Taylor polynomial:

b) Use Taylor's Inequality to estimate the accuracy of the approximation when x lies in the given interval. Round to five decimal places.

The 4th derivative (not sure if this is correct):

*nevermind on this part, can't use zero because a=0

I really need someone to please take me through each step of how to find the accuracy using Taylor's Inequality, I am not having luck understanding it from my notes. Thanks!!
