Design and implement a white$-$box test for a c$++$ program that computes the sine and cosine functions in a specialized manner. This program is going to be part of an embedded system running on a processor that does not support floating$-$point arithmetic. The program to be tested is attached. Your job is to test the functions sin and cos; you are to assume that the functions sin$0$to$45$ and sin$45$to$90$ have already been tested.
