Math.acos() Method - Math Functions
Math.acos() method of Math Functions in javascript.
How to get the arccosine value of a number in javascript?
Explanation
Object: Math
Method: Math.acos()
Description: To get the arccosine value for a number, we use this function. The function returns a value between 0 and PI radians. The parameter for asin() function should be between -1 and 1, if it exceeds the limit it returns "NaN".
<html>
<input type=button onclick="acosine()" name="button" value="Arc Cosine">
<script type="text/javascript">
function acosine(){
val = prompt("Enter a number to get the arccosine Value:", " ");
alert('Arc cosine of the number is::'+Math.acos(val));
}
</script>
</html>
In the above example for Math Functions,

Result:
In the above example for Math Functions,
- User is prompted to enter the value.
- Math.acos() method returns the arccosine value.
- If the radians exceeds the range -1 to 1, then returns "NaN".
