What are the sum and difference formulas for sine

👉 Learn all about sum and difference angle identities. In this video playlist, you will learn how to evaluate, solve, simplify and verify using sum and difference angle identities. We will evaluate using angles not found on the unit circle as well as sides of a triangle. We will work through multiple examples for the sum and difference angle identities of sine, cosine, and tangent.
