(a) Find an upper bound for the error in approximating e x using the 4 th Taylor polynomial about 0 for x in the interval [-. 2 , . 2]. (b) Find an upper bound for your error in 1(d). (c) Find the second Taylor polynomial for f ( x ) = x 3 + x based at b = 1. Find an interval J around b = 1 such that the error in approximating f ( x ) using T 2 ( x ) is less than 0 . 001 for all x in the interval J . (d) Let f ( x ) = 1 5-x and b = 0. Find an integer n so that the error in approximating f ( x ) with T n ( x ) for x in the interval [-2 , 2] is smaller than 0 . 009. 1...
