Consider the following function. f(x) = sec(x), a = 0, n = 2, â0.3 ⤠x ⤠0.3
(a) Approximate f by a Taylor polynomial with degree n at the number a. T2(x) =
(b) Use Taylor's Inequality to estimate the accuracy of the approximation f(x) â Tn(x) when x lies in the given interval. (Round your answer to six decimal places.) |R2(x)| â¤
