# Function csc

Calculate the cosecant of a value, defined as `csc(x) = 1/sin(x)`.

For matrices, the function is evaluated element wise.


## Syntax

```js
math.csc(x)
```

### Parameters

Parameter | Type | Description
--------- | ---- | -----------
`x` | Number | Boolean | Complex | Unit | Array | Matrix | null | Function input

### Returns

---- | -----------
Number | Complex | Array | Matrix | Cosecant of x


## Examples

```js
math.csc(2);      // returns Number 1.099750170294617
1 / math.sin(2);  // returns Number 1.099750170294617
