Lesson: Related and Correlated Angle Identities Mathematics

Start Practising

In this lesson, we will learn 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.

Lesson Plan

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.
