Solve the problem.What happens if you set B = -2? in the angle sum formulas for the sine and cosine functions? Do the results agree with something you already know?
What will be an ideal response?
If B = -2?, then cos (A + B) = cos A and sin (A + B) = sin A. Because the period of both of the sine and cosine functions is 2?, if B is replaced by a multiple of 2? the angle sum formulas must produce the same value as the sine or cosine function.
