Staff Review
Finally, a no-nonsense, "easy" way to understand the unit circle. Okay, so maybe the words "easy" and "unit circle" may never be said in the same sentence for you, but this lesson truly explains many trig / unit circle concepts in a way that is easy to remember. This lesson really is a stand-alone lesson when it comes to the unit circle. It includes much of what one should learn while including a couple of great resources, especially if you plan to continue on to Calculus. Many examples and applications round out a very complete and comprehensive lesson. If you're studying the unit circle, you do not want to miss this! -
