It is generally assumed in both mathematics and computing that an angle is measured in radians unless otherwise stated. I think all programming languages work that way, although some have an "angle mode" which can be set to degrees by default. Besides, it already covered in the documentation. The following text is taken from "info libm": `sin' and `cos' compute (respectively) the sine and cosine of the argument X. Angles are specified in radians.
