This PowerPoint™ lesson teaches students from Precalculus to Calculus about Multiple-Angle Formulas. The lesson requires no extra work on the teacher's part. Display it via a projector or interactive board/tv, click through the slides which include animation and natural transitions, while walking around the room engaging with your students. This is also a great tool for asynchronous learning (easy to share with students to work through on their own time, and perfect for making videos).

The lesson includes examples that cover:

• using double angle formulas to rewrite an expression
• find exact solutions of a trig equation involving double angles
• find the exact value of double trig functions

This is a wonderful resource for those new to teaching, or new to the material. It gives a great visual representation to student.
