For the tan curve you also need to remember that tan 45° = 1. 0 90 180 270 sin cos tan Steps to drawing the basic trig. graphs: Count each box as 15°. So you count 6 boxes for each 90 degree interval (0-90, 90-180, 180-270, and 270-360). Use the exact value from the quadrantal angle chart to plot your points on the graph.
