' This example finds the tangent of PI/4 and then uses the ATN function
' to find the arctangent of the value. Additional examples show how to
' find the cosine (COS), sine (SIN), and tangent (TAN) of a value.
 
' To try this example:
' 1. Choose New Project from the File menu
' 2. Copy the code example below to the code window
' 3. Press F5 to run the example
 
 CLS                                ' Clear the screen
 CONST PI = 3.141592653#
 PRINT ATN(TAN(PI / 4!)), PI / 4!   ' Output is:  .7853981635  .7853981635
 PRINT (COS(180 * (PI / 180)))      ' Output is:  -1
 PRINT (SIN(90 * (PI / 180)))       ' Output is:  1
 PRINT (TAN(45 * (PI / 180)))       ' Output is:  .9999999997050103
