Lesson Plan: Transformation of Trigonometric Functions Mathematics • 10th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to translate or stretch the trigonometric function and find the rule of a trigonometric function given the transformation.


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 đť‘Ą-axis and 𝑦-axis,
  • stretch the graph of a trigonometric function.


Students should already be familiar with

  • graphs of trigonometric functions.


Students will not cover

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