Rewriting. sin 2 x = sin x cos x + cos x sin x = 2 sin x cos x. we can compute the intersection: cos x = sin ( 2 x) is the same as. cos x = 2 sin x cos x cos x − 2 sin x cos x = 0 cos x ( 1 − 2 sin x) = 0. The product is zero if and only if cos x = 0 (which on [ 0, π / 2] occurs only at x = π / 2 ), or if 1 − 2 ...
