//--Returns the arccosine, an angle in radians

var lcMath = 'Math.Acos(-1): ' + Convert.ToString(Math.Acos(-1)) + '\n';

lcMath += 'Math.Acos(-.5): ' + Convert.ToString(Math.Acos(-.5)) + '\n';

lcMath += 'Math.Acos(0): ' + Convert.ToString(Math.Acos(0)) + '\n';

lcMath += 'Math.Acos(.5): ' + Convert.ToString(Math.Acos(.5)) + '\n';
