cosine

co·sine  (ksn) n. Abbr. cos 1. In a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse. 2. The abscissa at the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.

cosine cos = b/c
