The Unit Circle
|
This brief crash course unit is designed to expose you to radians and the unit circle. To do this, you will review special right triangles (45-45-90, 30-60-90), the three basic trigonometric functions (SohCahToa). From this review you will be introduced to polar graphing and radians. Finally, using all these concepts you will learn how to develop the unit circle.

Lesson 1 - Special Right Triangles
You will review the properties of the two special right triangles 30-60-90 and 45-45-90. Lesson 2 - SohCahToa
You will review the three trigonometric functions Sine, Cosine and Tangent. Lesson 3 - Polar Graphing
You will review the three trigonometric functions Sine, Cosine and Tangent. Lesson 4 - Radians
In this lesson you will discover a new concept called Radians. These are utilized much more than degrees in the higher-level of mathematics. Lesson 5 - The Unit Circle
This lesson takes all the concepts covered in the previous lesson and creates the unit circle. |
