# Interactive video lesson plan for: Fundamental Trigonometric Identities Intro & Proofs

#### Activity overview:

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.
