Unit 1: Trigonometry of General Triangles and Trigonometric Functions

Overview

In this unit you will understand the radian measure of an angle as the length of the arc on the unit circle subtended by the angle . You will also explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles, traversed counterclockwise around the unit circle.
