jmark · Answer

Angles and points on the circumference of a circle are the same thing. A point on the unit circle is the same as a right triangle formed by a radius to the point and its perpendicular to the x-axis. Hence sines and cosines which come from ratios of legs of a right triangle to the length of the hypotenuse are also the coordinates of the point on a circle of radius one.
