Consider the following points (a,4/5) and (b,4/5) on the graph of \( y = \cos(x)\) and (a,c) and (b,d) on the graph of \( y = \cos(x + \pi/6)\).
Furthermore, -pi/2
What has -pi/2 got to do with anything.
Please put the question altogether properly.
Sorry Melody, this was the problem that I was talking about which wasn't letting me type after the -pi/2. The thing should say "Furthermore, -pi/2
