Arithmetic. Using algebra makes finding a solution straightforward and familiar. Hint The appearance of 1 + cos x 1 + cos x suggests we can produce an expression without a constant term in the denominator by substituting x = 2t x = 2 t and using the half-angle identity cos2 t = 12(1 + cos 2t) cos 2 t = 1 2 ( 1 + cos 2 t). Integration.
