Unit Circle: One of the most basic things you need to know regarding trigonometry is how to find the Sine and Cosine of angles which are multiples of π/6 (30º) or π/4 (45º). The easiest way to accomplish this is to learn the unit circle.

Right Triangle Trigonometry:  Sections 1,2 and 6 of this web lesson are applicable – and there are exercises with solutions to help you practice.

Graphing: You need to be able to recognize and find equations for graphs of all the trig functions. This requires understanding amplitude and phase shift as well as having the basic graphs memorized. Notice that if you know the unit circle, you can use this information to find the important points on the basic graphs.

Solving Trig Equations: Very important -- and one of the more difficult topics.
