This is just a reminder that there is a math quiz on Monday, December 15. This quiz only covers mathematical proofs involving trigonometric identities.

A few pointers for the quiz:

- remember to decompose your identity into the left hand side and right hand side and analyze each individually
- manipulate each side until you reach a common solution (it helps to convert to sines and cosines first)
- once your LHS=RHS, you can conclude that the identity is true for all values of x, thus Q.E.D.
- do not forget to include your rationale; if you are substituting values or identities for other values or identities, mention which one you are using (Pythagorean, Quotient, etc)
