    I don't have word on my laptop but I'm assuming another answer can be found using the trig graphs.

    You don't have to go into amazing detail when drawing them, just a sketch will do. Aslong as you learn what they look like you should be fine (e.g. y=tanx repeats every 180 (or pi), y=sinx crosses through (0,0), (90, 1), (180, 0), (270, -1), (360, 0)).
