The following wiki applet is really great:
Thanks for the good work Eric.
However, the decoration on the radian value in the upper left hand corner is no the proper decoration for radians. Radians do not normally have any decoration with the value, here we have a degree decoration. This will be a distraction for the weaker student.
This is a bug that could be corrected possibly by adding a check box to allow angles to display in radians.
Would this be a reasonable request for an improvement?
