The Unit Circle and a Trig function in the Cartesian Plane

This applet helps connect the unit circle with a trigonometric function in the Cartesian plane. The applet also includes the circular motion of a particle describing relationships for the particles position, and tangential velocity with respect to the radius of the circle. The Period and Phase sliders do not affect the motion of the particle on the circle as they should.
