Returns the tangent of the angle passed as the argument.


The **`tan()`** function returns the tangent of the angle passed as the argument. The return value is a floating-point number.

## Syntax

```pseudo
$result = tan($angle);
```

Where `$angle` is the angle in radians.

## Codebyte Example

Using `tan()` to return the tangent of the angle in radians:

```codebyte/php
<?php
  $angle = 0.8; // Angle in radians
  $tangent = tan($angle);

  echo "Tangent of $angle radians: $tangent\n";
?>
```
