JAVASCRIPT acos() MATH OBJECT METHODS

The acos() math object method returns the arccosine of a number.

The general format is:

Math.acos(x)

Parameter x is required and must be an integer between -1 and 1. If it is out of this -1 to 1 range, NaN is returned.

Example:

<script type="text/javascript">

document.write(Math.acos(0.5) + '<br>');

document.write(Math.acos(-1) + '<br>');

document.write(Math.acos(-0.75) + '<br>');

document.write(Math.acos(-2));

</script>

The above will output:
