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

For some values of the argument, the values of the trigonometric functions can be obtained from geometric considerations (see Table 1). If we put n = 2, then: \L sin(2x)=2sin(x)cos(x) \L s i n ( 2 x) = 2 s i n ( x) c o s ( x) \L 2cot(x)sin2(x) =2( cos(x) sin(x) \L 2 c o t ( x) s i n 2 ( x) = 2 ( c o s ( x) s i n ( x) sin^2 (x) = 2sin (x)cos (x)\), \L x ≠ kπ),\ (\L k ∈ J \L x ≠ k π), \ ( \L k ∈ J.
