is 2pi...thats this thing. It goes all the way up
one and goes all the way down to -1 so it's
amplitude is 1. The options that immediately come to mind based on these
A and B. Sine and Cosine. The difference though is that a normal sign graph
begins at the origin
whereas a normal cosine graph begins at point zero one.
This one looks like it's the latter...so our answer is A.
