Tan Function

Returns the tangent of the angle specified.

Syntax

result = Tan( value )

Parameters

value

Double

The value (in radians) you want the tangent of.

Return Value

Result

Double

The tangent of value.

Notes


The Tan function returns the tangent of the angle (in radians) passed to it. If the angle is in degrees, multiply it by PI/180 to convert it to radians.


Examples

This example uses the Tan function to return the tangent of a number.

Dim d As Double
Const PI=3.14159265358979323846264338327950
d=Tan(45*PI/180) //returns 1.0
