Lesson Plan: Solving Trigonometric Equations with the Double-Angle Identity Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve trigonometric equations using the double-angle identity.
Students will be able to
- find the general solution, or find the solutions given a particular range, to a trigonometric equation that can be simplified using the double-angle identities (or the half-angle identities).
Students should already be familiar with
- angle sum and difference formulas,
- double- and half-angle identities.
Students will not cover
- triple-angle formulas (or higher order).
