By signing up, you'll get thousands of step-by-step solutions to your homework 2019-12-20 2018-02-24 2019-09-21 Integral of cos^2x or square of cos x or (cos x)^2. (cos x)^2 = 0.5[1+cos(2x)]. The integral of the expression on the right side is 0.5[x+0.5*sin(2x)]+C where C is constant of integration. So, Integral of cos^2x =0.5[x+0.5*sin(2x)]+C 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..
