# ACOTH

**The ACOTH function returns the hyperbolic arccotangent of a number.**

This function takes a single [Number](../../variable-data-types/the-number-variable-data-type) as input. It outputs that Number's inverse hyperbolic cotangent.

#### Declaration

```javascript
ACOTH(number) -> hyperbolic_arccotangent
```

&#x20;

#### Parameters

**number** (required, type: _Number_) The number to calculate the inverse hyperbolic cotangent of.

#### Return Values

**hyperbolic\_arccotangent** (type: _Number_) The inverse hyperbolic cotangent of the given number.

#### Examples

The following example returns the inverse hyperbolic cotangent of 5:

```javascript
ACOTH(5) -> 0.2027325540540822
```
