 UNIT 8 : TRIGONOMETRIC FUNCTIONS

 LESSON 2 : COMPOUND ANGLE FORMULAS

In this section we develop the compound angle formulas, which allow us to write the sine or cosine of (x + y) or (x y) in terms of the sines and cosines

of the individual angles x and y. See your text for proofs of the following formulas.
