Today in class we went over homework involving Identities. Incase you haven't learned them here is a link to Kelsey's Scribe Post about them.

These are Odd/Even Identities:

sin (–x) = –sin x cos (–x) = cos x tan (–x) = –tan x

csc (–x) = –csc x sec (–x) = sec x cot (–x) = –cot x

These are the Basic Identities:

These are the Pythagorean Identities:

sin² θ + cos² θ = 1

tan² θ + 1 = sec² θ

cot² θ + 1 = csc² θ
