# TAN

Returns the tangent of the specified angle.

## Syntax

`TAN`

(*angle*)

*angle* is a numeric expression that specifies an angle in radians.

You can express an angle in radians or degrees. The QBasic trigonometric routines support only radians. To convert from degrees to radians, use the following equation:

*radians* = 3.141593 * (*degrees*/180)

## Example

```
pi = 3.141593
PRINT TAN(pi / 4)
```
