## C++ asinh() function

asinh() function is a library function of cmath header, it is used to find the area hyperbolic sine of the given value, it accepts a number (x) and returns the area hyperbolic sine of x.

Syntax of asinh() function:

```    asinh(x);
```

Parameter(s): x – is the number/value whose area hyperbolic sine is calculated.

Return value: double – it returns double type value that is the area hyperbolic sine of the given number/value x.

Example:

```    Input:
float x = 2.45;

Function call:
asinh(x);

Output:
1.6285
```

### C++ code to demonstrate the example of asinh() function

```// C++ code to demonstrate the example of
// asinh() function

#include <iostream>
#include <cmath>
using namespace std;

// main() section
int main()
{
float x;

x = 1.0;
cout<<"asinh("<<x<<"): "<<asinh(x)<<endl;

x = 10.23;
cout<<"asinh("<<x<<"): "<<asinh(x)<<endl;

x = 2.45;
cout<<"asinh("<<x<<"): "<<asinh(x)<<endl;

return 0;
}
```

Output

```asinh(1): 0.881374
asinh(10.23): 3.02085
asinh(2.45): 1.6285
```
