Tan

Returns the tangent of an angle

Syntax
	KeyPgDeclareDeclare KeyPgFunctionFunction Tan ( KeyPgByvalByVal angle KeyPgAsAs KeyPgDoubleDouble ) KeyPgAsAs KeyPgDoubleDouble

Usage
	result = Tan( angle )

Parameters
	angle
		the angle (in radians)

Return Value
	Returns the tangent of the argument angle as a KeyPgDoubleDouble within the range 
	of -infinity to infinity.

Description
	The argument angle is measured in TutMathAnglesradians (not TutMathAngles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
