# Sin

## Using the Sin Function

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

The Sin function returns a Double specifying the sine of an angle.

=Sin( number )

number any valid number expression that expresses an angle in radians

The Sin function 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 hypotenuse.

The result lies in the range -1 to 1.

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 0.841470984807897.

Query

The results using a Query would be

```	SELECT Sin(1);
```

FORM

In a Form you could set the Default Value of a Textbox to

```	=Sin(1)
```
VBA

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

```	Private Sub Form_Load()
txtSin = Sin(1)
End Sub
```
