Submitted by IncludeHelp, on April 28, 2019

## C++ sinh() function

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

## Syntax

Syntax of sinh() function:

```sinh(x);
```

## Parameter(s)

x – is the number (hyperbolic angel) to be used to calculate the hyperbolic sine.

## Return value

double – it returns double type value that is the hyperbolic sine of hyperbolic angle x.

## Sample Input and Output

```Input:
float x = 2.45;

Function call:
sinh(x);

Output:
5.75103
```

## Example

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

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

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

x = -10.23;
cout<<"sinh("<<x<<"): "<<sinh(x)<<endl;

x = 0;
cout<<"sinh("<<x<<"): "<<sinh(x)<<endl;

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

return 0;
}
```

### Output

```sinh(-10.23): -13861.2
sinh(0): 0
sinh(2.45): 5.75103
```
