# Use the substitution in Exercise 59 to transform the integrand into a rational function of t and then evaluate the integral. ∫ d x 1 − cos x

To determine

To Find: Transform the integrand into a rational function of t and then evaluate the integral dx1cosx

Explanation

Calculation: Given dx1cosx

If t=tanx2 then by exercise 59 cosx=1t21+t2,dx=21+t2dt

dx1cosx=21+<
