# Tan Function

Determines the tangent of an angle. The angle is specified in radians.

Using the angle Alpha, the Tan Function calculates the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right-angled triangle.

Tan(Alpha) = side opposite the angle/side adjacent to angle

## Syntax:

`Sin (Number)`

## पैरामीटर

Number: Any numeric expression that you want to calculate the tangent for (in radians).

डिग्री को रेडियन में बदलने के लिए, Pi/180 से गुणा करें. रेडियन से डिग्री में बदलने के लिए, 180/Pi से गुणा करें.

Pi is approximately 3.141593.

## उदाहरण:

`' In this example, the following entry is possible for a right-angled triangle:`

`' The side opposite the angle and the angle (in degrees) to calculate the length of the side adjacent to the angle:`

`Sub ExampleTangens`

`' Pi = 3.1415926 is a pre-defined variable`

`Dim d1 As Double`

`Dim dAlpha As Double`

`    d1 = InputBox("Enter the length of the side opposite the angle: ","opposite")`

`    dAlpha = InputBox("Enter the Alpha angle (in degrees): ","Alpha")`

`    Print "the length of the side adjacent the angle is"; (d1 / tan (dAlpha * Pi / 180))`

`End Sub`
