The Unit Radius and the Unit Hypotenuse

Unit 7: Trigonometry: The Unit Circle
Lesson 2 of 9

Objective: SWBAT understand why radian measure is equal to arc length on the unit circle, and to make generalizations about sine and cosine when the length of the hypotenuse is 1.

Big Idea: The unit circle provides a rich landscape in which students can find surprising patterns as they have the experience of creating real mathematics.
