Sine Waves (Part 1 of 2)

This video, provided by Columbia Gorge Community College, is the first part of a two part lecture that discusses the properties of circles and sine waves. The main objective of the lecture is to "examine the circular origins of sinusoidal waves[,] convert between radians and degrees[, and] evaluate the sine and inverse sine functions using a scientific calculator." This video runs 22:44 minutes in length. The second part of the lesson is available to view separately.
