# Function coth
|
|
|
|
Calculate the hyperbolic cotangent of a value,
|
|
defined as `coth(x) = 1 / tanh(x)`.
|
|
|
|
For matrices, the function is evaluated element wise.
|
|
|
|
|
|
## Syntax
|
|
|
|
```js
|
|
math.coth(x)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
Parameter | Type | Description
|
|
--------- | ---- | -----------
|
|
`x` | Number | Boolean | Complex | Unit | Array | Matrix | null | Function input
|
|
|
|
### Returns
|
|
|
|
Type | Description
|
|
---- | -----------
|
|

|
|
|
|
|
|
## Examples
|
|
|
|
```js
|
|
// coth(x) = 1 / tanh(x)
|
|
math.coth(2); // returns 1.0373147207275482
|
|
1 / math.tanh(2); // returns 1.0373147207275482
|
