Tan

Returns the tangent of an angle

Syntax
   Declare Function Tan ( ByVal angle As Double ) As Double

Usage
   result = Tan( angle )

Parameters
   angle
      the angle (in radians)

Return Value
   Returns the tangent of the argument angle as a Double within the range 
   of -infinity to infinity.

Description
   The argument angle is measured in radians (not degrees).

   The value returned by this function is undefined for values of angle 
   with an absolute value of 2 ^ 63 or greater.

   Tan can be overloaded as operator to accept user-defined types.

Example
   Const PI As Double = 3.1415926535897932
   Dim a As Double
   Dim r As Double
   Input "Please enter an angle in degrees: ", a
   r = a * PI / 180   'Convert the degrees to Radians
   Print ""
   Print "The tangent of a" ; a; " degree angle is"; Tan ( r ) 
   Sleep

The output would look like:

   Please enter an angle in degrees: 75
   The tangent of a 75 degree angle Is 3.732050807568878
