The formula of the cos x 2 integral contains the integral sign coefficient of integration and the function as sine It is denoted by cos x 2 dx In mathematical form the integral of cos x2 is cos x 2dx x frac x 5 5 2 frac x 9 9 4 frac x We will use the cosine double angle identity in order to rewrite cos 2x Note that cos 2x cosx 2 they are different ways of writing the same thing cos 2x 2cos 2x 1 This can be solved for cos 2x cos 2x cos 2x 1 2 Thus intcos 2xdx int cos 2x 1 2dx Split up the integral
