Subtopic: Solving Trig Equations

Overview

Trigonometric equations are equations that contain trigonometric expressions. Because they are equations they can be solved for the variable which is usually the angle. These equations usually have multiple answers and you can check your answers by plugging back into the original equation or by graphing. In this lesson we start with some basic equations such as those that contain only a single trigonometric function.

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 6.1.1 Algebraically solve linear trigonometric equations
• 6.1.2 Algebraically solve quadratic trigonometric equations including those that factor and those that do not (e.g., quadratic formula needed)

Terminology

Define: trigonometric equation, linear trig equation, quadratic trig equation
