| Comment: | The idea behind this applet is very basic; I would rate it much higher if the angles were shown in degrees. My trig students start out with degree measure, and working with special triangles in radian measure adds an extra complication. |

| Comment: | I'll agree that the interface is rather pedestrian and lacks error trapping that could solidify the experience. However, as a student of calculus, I found this exercise to be a great refresher, given its use of radian measure. |
