Sine, Cosine, and the Unit Circle
2014-09-23 02:05
This applet visually demonstrates the relationship between the unit circle and trigonometric functions through geometric construction. On the unit circle, the coordinates of any point corresponding to an angle are exactly the cosine and sine of that angle. This dynamic illustration helps learners understand the geometric meaning of trigonometric functions in the coordinate system.
