In this video integrals involving powers of trig functions are illustrated. Usually this kind of integration involves some form of either u substitution or forces us to call upon various trig identities. See our earlier post on trig integrals for more discussion and examples.

Doing trig integrals is usually pretty simple. This is because of the cyclic nature of the derivatives of trig functions. Let’s recall that:
From here we can write down their anti-derivatives:
The minus sign comes about because we integrated the derivative of cos x to get this result. That is
but this was equal to minus sin x. [...]
