Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle.

This animation shows the unit circle and the value of three trigonometric functions in terms of the angle "a" in radians.

See how the functions sin, cos, and tan are defined from the unit circle, extending the definitions beyond the the 0 to 90 degrees that fit nicely inside a right-angled triangle. This is intended …
