### 4.1 Finding theta given the arc length and radius - Pre-Calculus help!

http://www.freemathvideos.com In this video series I show you how to find the arc length of a sector, the angle of a sector or the radius of a circle. We will use the formula S = r(theta) where S represents the length of the arc and r is the radius. Theta represents our angle. I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exaclty how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework.I post all of my videos on youtube but if you are looking for other ways to interact with me and my videos you can follow me on the following pages:
