Examples Use a coterminal angle to find the exact value of the six trigonometric functions of the following angles. 1. Doing one subtraction of , we obtain that = Thus, the two angles of and are coterminal. The angle is in the IV quadrant and has a reference angle of . Thus, by the theorem above, we have that. 2. ................
