JavaScript Math asinh() Method

Below is the example of the Math asinh( ) Method.

Example:

<script> 
   // Here different values is being used for 
   // getting hyperbolic sine function's values. 
   document.write(Math.asinh(3)); 
   document.write(Math.asinh(22)); 
   document.write(Math.asinh(-1)); 
   document.write(Math.asinh(1)); 
</script> 

Output:

 1.8184464592320668
 3.7847057630994327
-0.881373587019543
 0.881373587019543

The Math.asinh() method is used to get hyperbolic arc-sine of a number. The hyperbolic arc-sine is known by many names such as hyperbolic inverse sine and asinh. It is inverse of the hyperbolic sine function i.e, The inverse hyperbolic sine of any value say x is the value y for which the hyperbolic cosine of y is x.

if y = asinh(x)
then x = sinh(y)
We have,
acosh(x)=ln(x+√ x²+1 )

Syntax:

Math.asinh(x)

Parameters: This method accepts a single parameter as mentioned above and described below:

x: Here x is a number whose hyperbolic arc-sine is going to be calculated.

Return value: It returns the hyperbolic arc-sine of the given number.

Below examples illustrate the Math asinh() method in JavaScript:

Example 1: In this example a positive integer “2” is passed as a parameter in the math.asinh() function.It returns the hyperbolic arc-sine of the passed parameter.
```
Input : Math.asinh(2)
Output : 1.4436354751788103
```
Example 2: In this example “0” is passed as a parameter in the math.asinh() function.It returns the hyperbolic arc-sine of the passed parameter.
```
Input : Math.asinh(0)
Output : 0
```
Example 3: In this example a negative integer “-1” is passed as a parameter in the math.asinh() function.It returns the hyperbolic arc-sine of the passed parameter.
```
Input : Math.asinh(-1)
Output : -0.881373587019543
```

More example codes for the above method are as follows:
Program 1: Whenever we need to get a get hyperbolic arc-sine of a number that time we can take help of Math.asinh() function in JavaScript.

<script> 
    // Here different values is being used 
    // for getting hyperbolic cosine function's values. 
    document.write(Math.asinh(5)+"<br>"); 
    document.write(Math.asinh(12)); 
</script> 

Output:

 2.3124383412727525
 3.179785437699879

Program 2:

<script> 
    // Here different values is being used 
    // for getting hyperbolic cosine function's values. 
    document.write(Math.asinh('Geeks')+"<br>"); 
    document.write(Math.asinh('Geeksforgeeks')); 
</script>    

Output:

NaN
NaN
