The unit circle is one of the most helpful tools in trigonometry. Memorizing the reference angles along with their corresponding ordered pairs can help a student quickly determine the sine or cosine of the angle measure. For the unit circle to be truly helpful however, a student must be able to bounce back and forth from degrees to radians for each of the 16 reference angles. You will find cards testing this skill along with ordered pair identification and trig questions involving sine and cosine of the reference angles in both units. We suggest you use this set to test yourself for not only accuracy but speed as well. For when you can answer these questions with both, you will get the most out of this handy mathematical tool.
