Integral Of Cosine 2x

Integral Of Cosine 2x. What is the integral of cos^2(x)? Epsilonify Split the integral into two parts using the linearity of integration: ∫cos^2x dx = ∫ [ (1/2) + (1/2)cos (2x)] dx = (1/2)∫dx + (1/2)∫cos (2x) dx 3 This calculus video tutorial explains how to find the indefinite integral of cos(2x) using u-substitution

This calculus video tutorial explains how to find the indefinite integral of cos(2x) using u-substitution (Note that cos2x = (cosx)2, they are different ways of writing the same thing.) cos(2x) = 2cos2x −1 This can be solved for cos2x: cos2x = cos(2x) + 1 2 Thus, ∫cos2xdx = ∫ cos(2x) + 1 2 dx Split up the integral: = 1 2 ∫cos(2x)dx + 1 2 ∫dx The second integral is the "perfect integral:" ∫dx = x + C
