sin^2(x) + cos^2(x) = 1 (the other identities are easily derived from this). So most functions with some trig function can be solved using these 2 sets of identities? This function popped up towards the end of my derivatives chapter, and the book on trig barely covered those identities at all! :( (it mentioned the sin(a+b) identity but never used it).

Integrating Products and Powers of sin x and cos x. A key idea behind the strategy used to integrate combinations of products and powers of \(\sin x\) and \(\cos x\) involves rewriting these expressions as sums and differences of integrals of the form \(∫\sin^jx\cos x\,dx\) or \(∫\cos^jx\sin x\,dx\).
