$$1 - 2\sin^2 x = 2\cos^2 x - 1$$ Add $$1$$ to both sides of the equation: $$2 - 2\sin^2 x = 2\cos^2 x$$ Now $$ = -\cos x\int { \sin x \sin^2(x) } + \sin x\int { \cos x \sin^2(x) } .$$ You should finish evaluating the above integrals. Share. Cite.

Using the double angle formula for the sine function reduces the number of factors of sin x and cos x, but not quite far enough; it leaves us with a factor of sin2(2x).
