Lesson Plan: Related and Correlated Angle Identities Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to write trigonometric functions, like sine, cosine, and tangent, and their reciprocals in terms of cofunctions and use their properties to compare two trigonometric functions.

Objectives

Students will be able to

  • express trigonometric functions and reciprocal trigonometric functions in terms of cofunctions
    • including translations,
  • identify equivalent angles of the trigonometric functions sin, cos, and tan and the reciprocal trigonometric functions cosec, sec, and cot,
  • recognize the equivalence of two trigonometric functions using the known properties of the function and equivalence relationships.

Prerequisites

Students should already be familiar with

  • periodicity of trigonometric functions.

Exclusions

Students will not cover

  • evaluating trigonometric functions,
  • inequalities.
