Here's what you should know for the quiz on Tues/Wed:

How to find an exact value (ex. tan75)
Work in reverse using the sum/difference identities (ex. cos3xcosx-sin3xsinx)
PROOFS! Like any proof we have done in class
Finding solutions to an equation in the interval 0 to 2 pi
Writing an expression using only sinx and cosx.
Finding exact values using half-angle identities.

Clearly there are more than just 6 questions, these are just the topics covered.
