Question:

The third remainder for f (x) at x = 0 is

where c is a number between 0 and x. Let f (x) = cos x, as in Check Your Understanding Problem 11.1. 

(a) Find a number M such that | f (4)(c)| ≤ M for all values of c.

(b) In Check Your Understanding Problem 11.1, the error in using p3(.12) as an approximation to f (.12) = cos .12 is given by R3(.12). Show that this error does not exceed 8.64 * 10-6.
