should do. The problem is that is often used to

denote the function.

Your amplitude is OK, but the period is wrong. It is true that thei have the hardest time at drawing graphs. i know how to find the amplitude (which is 2 here) and i know that the period=2pi/B (so the period is pi here. but i cant seem to figure out how to find the phase shift or how to draw the entire graph from just an equation. does anyone have any tips?

period of is , but in your plot

the period is 2, so:

Now so:

.So any solution of:

will be a solution for the phase, presumably you want one in

either or .
