# Tan

## Using the Tan Function

In this tutorial you will learn how to use the Tan Function.

The Tan function returns a Double specifying the tangent of an angle.

=Tan( number )

number any valid number expression that expresses an angle in radians

Tan takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the side adjacent to the angle.

To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.

In this example we will use 1.

The result is 1.5574077246549.

Query

The results using a Query would be

```	SELECT Tan(1);
```

FORM

```	=Tan(1)
```
VBA

In a Form add a TEXTBOX control and rename it "txtTan", then you could add the following in the Load Event.

```	Private Sub Form_Load()
txtTan = Tan(1)
End Sub
```
