Sine/Unit Circle Relationship
This applet demonstrates the relationship between the central angle of a unit circle (left), the length of the opposite side of the right triangle formed by the vertical segment from C to the x-axis, and the graph of the sine function (right, with the horizontal axis tied to the central angle of the unit circle: the arc length 'h' is tied to the segment FG).
