Lesson Handout #1, 3, 9, (ODD), 27, 28, (ODD), (EOO)

Unit Circle Trigonometry Objective Students will know how to identify the unit circle and its relationship to real numbers. Students will know how to evaluate trigonometric functions of special angles and use reference angles to evaluate trigonometric functions.

Put the following values in order from least to greatest.

The Unit Circle!!! Center: Origin (0,0) Radius: 1 unit

Standard Position - an angle whose vertex is the origin and the initial side coincides with the positive x-axis.

Coterminal Angles - angles that have the same initial and terminal sides.

What are quadrantal angles??? Convert each radian measure to degrees.

Evaluate the following. If a value is undefined, state “Undefined.”
