Answers

The identities for $\cos (A+B)$ and $\cos (A-B)$ can be used to find exact values of expressions like cos $195^{\circ}$ and $\cos 255^{\circ},$ where the angle is not in the first quadrant. Work Exercises $39-42$ in order, to see how this is done. Use the identity for $\cos (A-B)$ to find $-\cos 15^{\circ}$.
