For the best answers, search on this site https://shorturl.im/ttuLB. sin (2x + 2x) = 2 sin 2x cos 2x sin 4x = 2 (2 sin x cos x)(2 sin x cos x ) sin 4x = 8 sin^2 x cos^2 x sin 4x = 8 sin^2 x (1 - sin^2 x) sin 4x = 8 sin^2 x - 8 sin^4 x

cos 2 2x – cos 2 6x = sin 4x sin 8x. Solution: We get = [2 cos 4x cos (-2x)] [-2 sin 4x sin (-2x)] It can be written as = [2 cos 4x cos 2x] [–2 sin 4x (–sin 2x)] So we get = (2 sin 4x cos 4x) (2 sin 2x cos 2x) = sin 8x sin 4x = RHS. 14. sin 2x + 2sin 4x + sin 6x = 4cos 2 x sin 4x.
