Question:

We estimate integrals using Taylor polynomials. Exercise 72 is used to estimate the error.

Let Tbe the fourth Maclaurin polynomial for ƒ(x) = cos x.
(a) Show that

| cos x - T4(x)|  12 6!  [0,1/1 for all x 0, xe

T4(x) = T5(x).

1/2 (b) Evaluate size of the error. T4(x) dx as an approximation to 1/2 cos xdx. Use Exercise 72 to find a



Data From Exercise 72

Let L > 0. Show that if two functions ƒ and g satisfy |ƒ(x) − g(x)|

L'o  f(x) dx - * 8(x) dx/dx < L(b-a
