Integration using trig identities or a trig substitution. Integrals of trigonometric functions calculus socratic. Type in any integral to get the solution, steps and graph this website. Since the derivatives of \sinx and \cosx are cyclical, that is, the fourth derivative of each is again \sinx and \cosx, it is easy to determine their integrals by logic. Then the integral contains only powers of secant, and you can use the strategy for integrating powers of secant alone. In order to integrate powers of cosine, we would need an extra factor.
