Aug 06, 2020 · Section 1-3 : Trig Functions. Determine the exact value of each of the following without using a calculator. Note that the point of these problems is not really to learn how to find the value of trig functions but instead to get you comfortable with the unit circle since that is a very important skill that will be needed in solving trig equations.

Step 2. Find the right triangles. Trigonometry gives us tools that deal with right triangles - where one interior angle is 90°. ( Only two trig tools deal with non-right triangles - the Law of Sines and the Law of Cosines.) The first thing to do is determine if there are any right triangles. Many times you have to assume the right angles.
