Integrals of Trig Functions Using LogsRecall:Trig Derivatives Trig Integrals
Note: Since the derivative of trig function does NOT always yield another basic trig function we have basic trig functions that do NOT have integral formulas.
Problem:
BASIC TRIG Integrals
Another application of logarthmic integration is deriving formulas of integration for and all other secondary trig functions namely: , , (Makes sense since these all can be expressed as rationals)
Integrate:

Important: Especially in trig if integration by substitution is not working, try rewriting the function into a form for which integration is possible using all your trig identities and formulas:(
