Students will practice simplifying trigonometric expression with this set of two relay puzzles. Students must simplify the expression, then pass their answer to the next problem to simplify the next expression. Relays included:

• **Relay 1: **Basic identities (reciprocal, quotient, Pythagorean)

• **Relay 2: **Sum and Difference of Angles Identities, Double-Angle and Half-Angle Identities (along with the basic identities in relay 1)

Both relays require factoring, combining fractions, distributing, and another algebraic manipulation.
