単位円: 数分で覚える方法。

This class will provide a quick and easy way to memorize the unit circle. I will explain a very simple method for students to remember all the points on the unit circle. Students will have guided practice with me. This is not an introduction to the unit circle. Students should already have learned what the unit circle is in class. While many teachers do not want students to memorize the circle, it is very easy to do so in order to do well on any test that includes the unit circle, including the ACT.
