3.2 Trigonometry

This paper introduces trigonometry by breaking it into two sections:

  • Understanding trigonometric functions
  • Using trigonometry to solve problems in context.

It provides details of the knowledge students should have and some of the misconceptions they may hold. Examples are given to illustrate what these misconceptions may look like, how to address them, and support teachers in developing pedagogical and content knowledge.
