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

• Example:
 ``
• 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.
