Expert Answer:
Trigonometric functions are sometimes called circular functions. This is because the two fundamental trigonometric functions the sine and the cosine are defined as the coordinates of a point P travelling around on the unit circle of radius 1 .
As P moves around the circle of radius 1, the input variable the angle q changes. The outputs cos(q) and sin(q) give the x and y coordinates of P, respectively.
