## Unit Description

This unit you will use formulas to find the value of non-common unit circle measures without using a calculator. You will also explore the double angle concept and how to calculate these angle values. Finally, you will use your prior knowledge and skills to solve trigonometric equations for the angle measure.

## Unit Objectives

1. To use the half angle formulas to find non-common angle measures around the unit circle.

2. To explore the concept of double angles and use formulas to calculate their values.

3. To use factoring skills to solve trigonometric equations for the missing angle measures

which are usually denoted by the Greek symbol theta.
