An alternative: cos 3 x + sin 3 x = (1/2)(cos x + sin x)(2 - sin 2x) = (1/2)(cos x + sin x)(2 - 2sin x cos x) = ( where F is an antiderivative of f. Example. To compute ∫sin(2x)cos(2x)dx, let u=sin(2x)du=2cos(2x)dx. Then ∫sin(2x)cos(2x)dx=∫12sin(2x)[2cos(2x)dx]=∫12 ... (a) -2 ln |x| + ln(x2 + 1) + arctan(x) + C. (b) ln(2 +. /. 3) - ln(. /. 2 + 1).
