Topic: Trigonometric Equations
Subtopic: Solving Trig Equations


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.


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


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