16 Special Points on the Unit Circle
The 16 Special Points on the Unit Circle are all generated with either the 45°-45°-90° or the 30°-60°-90° Special Triangles in different orientations. You can see all of them in sequence by clicking the animate button.
But ALL the points on the Unit Circle each have angles and values for all six Trig Functions. The 16 Special Points are useful for graphing, etc.
