I think that I made a mistake...I am going to go back and fix that and come back...the problem posted on the first page of this thread shows the curve going up to 2...
you labeled a point on the graph to be , how is it that the amplitude is 2? (you do not label a grid using coordinates, so if that's what you tried to do, you are double wrong on this problem. you define your grid on your axis, anyone will assume that any coordinate point you write applies to the curve)
