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
