To sum up, only two of the trigonometric functions, cosine and secant, are even. The other four functions are odd, verifying the even-odd identities. The next set of fundamental identities is the set of reciprocal identities, which, as their name implies, relate trigonometric functions that are reciprocals of each other. Reciprocal Identities.Warm Up Simplify the following expressions to a single trig ratio. 1. 2. 3. Strategies for verifying trig identities: • Re-write reciprocal functions: change everything to sines and cosines • Add or “un-add” expressions • Multiply by the conjugate • Simplify complex fractions • Factor • Use Pythagorean Identity
