Tan

FreeBASIC

Tan
 
Returns the tangent of an angle

Syntax
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.

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
