JavaScript ACOS

The JavaScript ACOS function a Math function that calculates the trigonometric Arc Cosine for the specified expression. Arc Cosine also called the inverse of a COSINE Value. The syntax of the JavaScript Acos Function is

Math.acos(number);

If the number argument is not a number or outside the range -1 and 1, JavaScript ACOS function will return NaN.
