Lesson: Solving a Trigonometric Equation Mathematics

In this lesson, we will learn how to solve a trigonometric equation using factoring or squaring.

Lesson Plan

Students will be able to

recall that dividing through by a term involving a variable could result in the loss of solutions,
find the solution set, or general solution of trigonometric equations, over a specified range using factoring or squaring; this includes using substitution to transform a trigonometric equation into a quadratic equation and solving using standard methods.
