Setting Up the Unit Circle Part 2

In a 2 part video I introduce the basic functions of Trigonometry ( Sine, Cosine, and Tangent ) and explain the design and use of the unit circle. I also review the definition of a reference angle. * NOTE: The last angle is suppose to be 330 NOT 333:) (Thank you to al those students that are paying attention:) Check out http://www.ProfRobBob.com, there you will find my lessons organized by class/subject and then by topics within each class.
