Thinking is Learning

The first page of these notes define an identity and derive some of the trigonometric identities. The second page of these notes have examples of simplifying trigonometric expressions using identities. The third page of these notes verify identities. Answer key included!

These notes are scaffolded to support students in creating their own notes about simplifying trigonometric expressions (using reciprocal, quotient, and Pythagorean identities). A completed example is included for students that are absent or have the accommodation where they receive a completed copy of notes. This would best be used after students have experienced working some examples during a time of productive struggle.
