Unit Circle 1.0 is a simple program which displays the trigonometric values, degree measures, and radian measures of angles that are multiples of pi/6 rad. (30 Deg.) It should be very helpful to Precalculus and Calculus students who often forget the values of these angles.

Program operation: Run the program. When you see the values for the angle zero displayed on the LCD, press F1 or F2 to cycle through the different angles. Press F5 to exit the program.
