I introduce and prove the Fundamental Trigonomic Identities...the Quotient Identities, Reciprocal Identities, and the Pythagorian Identities.
I like this tip!!! Darren Bonura: My teacher taught us "No Co-Co" as in Cosine doesn't equal Cosecant. Just a helpful way to remember it. That way Cosine has to equal Secant and thus Sine equals Cosecant.
