# 
## Syntax
```swift
sinh(num)
```
## Parameter
This function requires a number that represents an angle in radians as a parameter.

The following formula converts degrees to radians.
```swift
radians = degrees * ( pi / 180.0 )
```

## Return value
`sinh()` returns a number's hyperbolic sine, which is sent as a parameter.

## Example
The code below shows us how to use the `sinh()` function in Swift:

import Swift
import Foundation

//positive number in radians
print("The value of sinh(2.3) :", sinh(2.3));

// negative number in radians
print("The value of sinh(-2.3) :", sinh(-2.3));

//converting the degrees angle into radians and then applying sinh()
// degrees = 90.0
// PI = 3.14159265
print("The value of sinh(90.0 * (PI / 180.0)) :", sinh(90.0 * (Double.pi / 180.0)));
