The in-built **```asinh()``` function** from the ```math``` module in Python is used to return the inverse hyperbolic sine of a number in radians.

Figure 1 shows the mathematical representation of the ```asinh()``` function.

# Syntax

```python
math.asinh(x)
```
## Parameter

This function requires a positive or negative ```number``` as a parameter.

## Return value

```asinh(x)``` returns a **```float``` value** that is the inverse hyperbolic sine of a number sent as a parameter.

import math

#Parameter as a positive number
print ("The value of asinh(5) is:", math.asinh(5))

#Parameter as a negative number
print ("The value of asinh(-7) is:", math.asinh(-7))
