Algebra 2 11.08a - Sine and Cosine on the Unit Circle

Understanding the sine and cosine of an angle on the unit circle. In this video, I am trying to help the students get inside the head of an engineer or mathematician, so that they can understand some different and useful ways of thinking about the meaning of sin(theta) and cos(theta) in light of angles on the unit circle. From the introductory trigonometry lessons in the Algebra 2 course by Derek Owens. More info on this course and others can be found at http://www.DerekOwens.com and http://www.LucidEducation.com
