To find the hyperbolic arcsine of a number, we can use the JavaScript **asinh()** function from the math module.

`Math.asinh(x)`

In JavaScript, we can easily use trigonometric functions with the Python math module. The JavaScript math module allows us to perform trigonometry easily and in addition to regular trigonometry, we have access to the hyperbolic trigonometry functions.

With the JavaScript math module, we can find the hyperbolic arcsine of a number easily.

To find the hyperbolic arcsine of a number, we can use the JavaScript **asinh()** function from the math module.

Below is the JavaScript syntax to find the hyperbolic arcsine of a number.

`Math.asinh(x)`

The input to the **asinh()** function must be a numeric value. The return value will be a numeric value.

```
console.log(Math.asinh(10))
console.log(Math.asinh(0))
console.log(Math.asinh(-5.32))
// Output:
2.99822295029797
0.0
-2.3733388650599814
```

## Finding the Inverse Hyperbolic Sine of a Number in JavaScript

The JavaScript math module also provides us trigonometric functions to find the inverses of the common trigonometric functions. The asinh() function allows us to find the inverse of the hyperbolic sine of a number.

Below, we show that if we pass a number to **sinh()** and then call the JavaScript **asinh()** function, we get back the same number.

```
console.log(Math.asinh(Math.sinh(100)))
// Output:
100.0
```

Hopefully this article has been beneficial for you to understand how to use the math **asinh()** function in JavaScript to find the hyperbolic arcsine of a number.
