Question is [math]\displaystyle\int(sin^3x)(cos^2x)dx[/math] The trigonometric identity is used: [math]sin^2x+cos^2x =1 [/math]and [math]cos2x=2cos^2x-1[/math] Now Question can be written as : [math]\displaystyle \int(1-cos^2x)cos^2xsin 1/8 integral (1-2cos 4x - cos 2 4x-2 cos 4x-4cos 2 4x - 2 cos 3 4x - cos 2 4x - 2 cos 3 4x - cos 4 4x 1/8 integral (1-4cos4x-6cos 2 4x - 4 cos 3 4x -cos 4 4x dx) I stopped here because it wouldn't give me the answer I needed. To integrate cos^22x, also written as ∫cos 2 2x dx, cos squared 2x, (cos2x)^2, and cos^2(2x), we start by considering standard trig identities to simplify the integral. We recall the double angle formulae and rearrange it for cos 2 x. We recall the Pythagorean identity and rearrange it for sin 2 x.
