    5.4 - Using the addition of two angles formula and sine

    http://www.freemathvideos.com This math problem was filmed during online live instruction for class. This is my way of providing a free tutorial for students that want to learn math from an online tutor. Please visit my website listed above where you can view all of my math lessons. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a live classroom. These videos are intended to help you learn how to solve math problems, review how to solve math problems, study for a test, finish your homework and get a better grade in your math class. Please write to me and let me know how I can better help you!

    5.4 How to apply the sum of angles with the sine of an angle not on unit circle

    http://www.freemathvideos.com In this video tutorial we will explore how to use the sum and difference formula for sine cosine and tangent. We will use these formulas as the addition or subtraction of two angles that we can evaluate the exact value for. We will not explore the proof for these formulas but rather apply them to problems that ask us to evaluate, solve, verify and simplify.
