FTrig

FTrig is a utility for fast approximate trigonometric calculating on javascript, based on this article. FTrig can be used with Node.js, RequireJS or directly in the browser.

A FTrig instance is create as:

var trig = new FTrig(FTrig.LOW); // faster, less accurate
// or
var trig = new FTrig(FTrig.HIGH); // more, more accurate

trig.sin(Math.PI/4);
trig.cos(Math.PI/4);

A FTrig instance provides 2 functions: sin and cos, as alias of the 4 main functions: sinLow, cosLow for FTrig.Low and sinHigh, cosHigh for FTrig.High.
