En primitiv funktion till f (x) = cos 2x blir. Man får inte glömma att ta hänsyn till den inre derivatan 2. Man gör tvärtom som vid derivering. Man dividerar alltså med

I = sin3x cos4xdx = sin2x cos4x sin xdx. sin2x = 1 − cos2x. 22 1 (sin 7x − sin 3x) dx sin 2x cos 5xdx = 2 1 −cos 7x − −cos 3x +C = cos 3x

Cos^2x-sin^2x = cos 2x. so cos 2x = 0. so 2x = pi/2 or 3pi/2. 2x = 2npi + pi/2 and 2npi + 3pi/2.
