Lesson: Transformation of Trigonometric Functions

Mathematics

In this lesson, we will learn how to translate or stretch the trigonometric function and find the rule of a trigonometric function given the transformation.

Plan

Objectives

Students will be able to

  • find the coordinates of a point on a trigonometric graph after it has been transformed,
  • translate the graph of a trigonometric function in the directions of the 𝑥-axis and 𝑦-axis,
  • stretch the graph of a trigonometric function.

Prerequisites

Students should already be familiar with

  • graphs of trigonometric functions.

Exclusions

Students will not cover

  • rotations of graphs of trigonometric functions,
  • reflections of graphs of trigonometric functions,
  • reciprocal trigonometric functions.
