Method

doublecosToSin(double angle, double cos)
Fast way of computing sin(x) from x and cos(x). 
if ((-1e-5 < cos && cos < 1e-5) || cos > 0.99999 || cos < -0.99999) {
    return Math.sin(angle);
angle = normAngle(angle);
final double s = Math.sqrt(1 - cos * cos);
return (angle < Math.PI) ? s : -s;
