Radians and Degrees

This trigonometry video tutorial provides a basic introduction into radians and degrees. It explains the definition of the radian and how to calculate the angle measure in radians given the arc length of a circle and the length of the radius. This video also explains the process of converting degrees to radians and converting radians to degrees. To convert from degrees to radians, multiply the angle measure in degrees by pi divided by 180. To convert from radians to degrees, multiply the radian measure by 180 over pi. To calculate the angle measure in radians - divide the arc length by the length of the radius of the circle. This video also explains how to draw angles in standard position using radians instead of degrees. It explains the location of common angles such as pi/4, 3pi/4, 5pi/4, and 7pi/4 and more. This video contains a lot of examples and practice problems.
