The ** sinh() function** returns the

The figure below shows the mathematical representation of the `sinh()`

function.

The

`math.h`

header file is required for this function.

```
double sinh(double num)
```

This function requires a `number`

that represents an `angle`

in `radians`

as a parameter.

Use the following formula to convert

`degrees`

to`radians`

```
radians = degrees * ( PI / 180.0 )
```

`sinh()`

returns the
