### Deriving Values on the Unit Circle

Deriving Values on the Unit Circle. In this video, I show how to actually DERIVE the values in the first quadrant of the unit circle (so that you are not just memorizing them!). All you are really doing is using a bit of geometry and the pythagorean theorem; nothing worse than that!**Sorry! The table shakes a bit! I am not at home using my usual set up and I have a shaky table - trying to figure out how to make it more stable!**
