# Interactive video lesson plan for: Pre-Calculus - Learn how to use period as an aide to evaluate sine for a negative angle

#### Activity overview:

http://www.freemathvideos.com In this video playlist you will start by learning how to sketch angles in standard form in radians and degrees. We will then learn how to convert between angles in radians and degrees. Next we will discuss the six trigonometric functions, sign, cosine, tangent, cosecant, secant, and cotangent. We will learn how to evaluate for each function using right triangles as well as the unit circle. We will discuss arc length, and how to find the angle given the value of a trigonometric expression.
