# VBA TAN Function (Syntax + Example)

- Written by Puneet

Contents

The VBA TAN function is listed under the math category of VBA functions. When you use it in a VBA code, it calculates the tangent of a supplied angle. You can learn more about tangent from here. You just need to specify the angle and it will calculate the tangent.

Tan(Number)

## Arguments

• Number: The number to specify the angle for which you want to get the tangent.

## Example

To practically understand how to use the VBA TAN function, you need to go through the below example where we have written a vba code by using it:

``````Sub example_TAN()
Range("B1").Value = Tan(Range("A1"))
End Sub``````

In the above code, we have used the TAN to get the tangent of the angle that we have in cell A1 (1.46) and it returned 8.726459 in the result.

## Notes

• You can multiply the result returned by the TAN with pi/180 to convert it into a radian and 180/pi to convert it into degrees.
• If the value specified is a value other than a number or a number that can’t be recognized as a number, VBA will return the run-time 13 error.
