# Lesson Plan: Simple Trigonometric Equations Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find angle measures given interval and function values.

#### Objectives

Students will be able to

• solve simple trigonometric equations by applying invoice operations, simple algebraic methods, or simple trigonometric identities,
• recognize and use the periodicity of trigonometric functions to identify all of the solutions to a trigonometric equation in a specified range or identify the general solution (this includes using the graphs of trigonometric functions to identify solutions),
• solve equations involving the reciprocal trigonometric functions (secant, cosecant, and cotangent).

#### Prerequisites

Students should already be familiar with

• reciprocal trigonometric functions,
• graphs of trigonometric functions,
• Pythagorean and cofunction identities.

#### Exclusions

Students will not cover

• solving equations using factoring or squaring,
• double- or half-angle identities.
