To integrate sin^22x cos^22x, also written as ∫cos 2 2x sin 2 2x dx, sin squared 2x cos squared 2x, sin^2(2x) cos^2(2x), and (sin 2x)^2 (cos 2x)^2, we start by using standard trig identities to change the form.. We recall the Pythagorean trig identity and rearrange it for cos squared x to make [1]. We recall the double angle trig identity and rearrange it for sin squared x to make [2].
