};

Trigonometric function that calculates the cotangent of a specific value in radians.

## Syntax

```sql theme={"theme":{"light":"github-light","dark":"github-dark"}}
COT(<value>)
```

## Parameters

| Parameter | Description                                                       | Supported input types |
| :-------- | :---------------------------------------------------------------- | :-------------------- |
| `<value>` | The value which the `COT` function will be applied to in radians. | `DOUBLE PRECISION`    |

## Return Types

`COT` returns a value of type `DOUBLE PRECISION`.

## Example

The following query calculates the cotangent of 1.57 radians. 1.57 is approximately pi/2:

<QueryWindow
  content={{
"sql": "SELECT COT(1.57) as result;",
"result": {
"data": [
  [
    0.0007963269632231926
