Hey
How come when i try to graph sqrt(2) cos(2x+pi/4) I can't simply draw sqrt(2) cos(2x) and shift the curve to the left by pi/4. I think the curve is being shifted to the left by pi/8 but I don't properly understand why.
Thanks![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
