FP1 method with general solutions is the easiest way to solve trig equations you'll encounter in C2, C3 and C4.

Watch from 4.01a to 4.04b. General solutions start at 4.02a, and he has some questions in a few vids right after those.

Anything else with trig equations is the just the matter of knowing the identities and getting everything in terms of the same variable which comes from practice.
