# C++ Math asinh()

The function computes the arc hyperbolic sine of an angle given in radian.

Where, an arc of hyperbolic sine is the inverse of hyperbolic sine.

sinh-1x = asinh(x);

## Syntax

Suppose an angle given in radian is 'x':

## Parameter

x: The value whose arc hyperbolic sine is to be computed.

## Return value

The function returns the arc hyperbolic sine of an angle given in radian.

## Example 1

Let's see the simple example when the value of degree is integer type.

Output:

```Value of degree is : 90
sinh(x) : 2.2993
asinh(x) : 1.23298
```

In this example, asinh() computes the arc hyperbolic sine of x and returns the value 1.23.

## Example 2

Let's see the simple example when the value of degree is float type.

Output:

```Value of degree is : 45.5
sinh(x) : 0.879727
asinh(x) : 0.727759
```

In this example, asinh() function computes the arc hyperbolic sine of x and returns the value 0.72.
