# COTH

**The COTH function returns the hyperbolic cotangent of a number.**

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

#### Declaration

```javascript
COTH(number) -> hyperbolic_cotangent
```

&#x20;

#### Parameters

**number** (required, type: _Number_) The number to calculate the hyperbolic cotangent of.&#x20;

#### Return Values

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

#### Examples

The following example returns the hyperbolic cotangent of 1:

```javascript
COTH(1) -> 1.3130352854993319
```
