Web14 mar. 2012 · You can use a function like this to do the conversion: function toDegrees (angle) { return angle * (180 / Math.PI); } Note that functions like sin, cos, and so on do not return angles, they take angles as input. It seems to me that it would be more useful to you to have a function that converts a degree input to radians, like this: WebSin A. Sin B = [Cos (A – B) – Cos (A + B)]/2 Sin A. Cos B = [Sin (A + B) + Sin (A – B)]/2 Cos A.
