Product Description
In this packet, students will learn:

1) a geometric way to prove the formula for finding the sine and cosine of the sum of two angles.

2) a geometric way to prove the formula for finding the sine and cosine of a double angle

Once the proofs have been completed, students have a better appreciation of the formulas they will be using.

I have also included 2 practice pages that students can use to practice using the sum and double angle formulas.

I have also included two forms of a quiz that I use when I test these topics. However, please note that these quizzes contain additional questions about using the half angle formulas and proving trig identities.
