Radian Measure and the Unit Circle
The Unit Circle and Circular Functions
Grade Level:
11
Subject:
Trigonometry
Topic:
3.3 The Unit Circle and Circular Functions
Objective:
The students should be able to define the trigonometric functions for a Unit Circle and use it to find Values of Circular Functions.

Reflection:
We completed the unit circle in class, explaining the coordinates for x and y and used it to find the exact circular function values. Need to allow students to use this tool in class to help answer questions without memorization. Next time students complete a blank Circle before test showing understanding of the unit circle and applications for use. Real angles and real values confused students when using the calculator. Need to give clear examples and get students interpretation of what is given.
Prep:
Handout a new unit circle to continue defining real values of the coordinates for each angle of the circle.
