The thing with your drawing of the functions is that you've just drawn straight lines. They should be curves. You should use a program that's a bit better than paint at drawing functions. I myself use graph 4.3. Look the functions up there.
Anyways, it should be like this:
graph one should look like a periodic curve that repeats itself every 360 degrees, i.e. it goes from 1 to -1 on the y-axis after 180 degrees, and then goes back to 1 etc, starting at the point (0,1).
Graph two should look like graph one, except for the fact that it's displaced by 1 in a positive direction on the y-axis.
Graph three should look like graph one also, but should be displaced by 30 degrees to the left.
Best wishes, and good luck with trigonometry!
