## Unit 4: Trigonometry of General Triangles and Trigonometric Functions

▼

### Overview

*In this unit, we will continue our study of trigonometry that was begun in Math II. We will extend the domain of trig functions to all real numbers, exploring their graphs and applying them to solve various problems. We will use the unit circle to explore symmetry and the period for trig functions, allowing us to simplify the calculations of many trig values.*
