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