USING IDENTITIES TO EVALUATE TRIG VALUES
Today we will work with Identities to determine the values of trig functions given certain information.
Process1. Determine which Quadrant the terminal side is in.2. Write down all 6 trig functions =3. Fill in what you know.4. Use the appropriate identities (and Pythagorean
Theorem) to determine the remaining trig values.
