Math.acosh( ) In JavaScript

The Math.acosh() function in Javascript is used to return the hyperbolic arc-cosine of a number.
Math.acosh (x) = arcosh(x) = y ≧ 0 such that cosh (y)=x
acosh() is a static method of Math, therefore it is always used as Math.acosh(), rather than as a method of a Math object created.

Syntax:

Math.acosh(value)

Parameters: This function accepts single parameter value which is the number whose hyperbolic arc-cosine you want to know.

Returns: It returns the hyperbolic arc-cosine of the given number and if the parameter passed is less than 1, it returns NaN.

Examples:

Input  : Math.acosh(1)
Output : 0

Input  : Math.acosh(0)
Output : NaN

Input  : Math.acosh(-1)
Output : NaN

Input  : Math.acosh(2)
Output : 1.3169578969248166

Example 1: When 1 is passed as a parameter.

<script type="text/javascript">

document.write("Output : " + Math.acosh(1));

</script>
Output:
```
Output : 0
```
Example 2: When 0 is passed as a parameter.

<script type="text/javascript">

document.write("Output : " + Math.acosh(0));

</script>
Output:
```
Output : NaN
```
Example 3: When a number less than 0 is passed as a parameter.

<script type="text/javascript">

document.write("Output : " + Math.acosh(-1));

</script>
Output:
```
Output : NaN
```
Example 4: When 2 is passed as a parameter.

<script type="text/javascript">

document.write("Output : " + Math.acosh(2));

</script>
Output:
```
Output : 1.3169578969248166
```
