The program is designed to help students learn to "think" in radian measure on the unit circle and learn to place the exact coordinates in their proper place. The idea is after playing with the wedges, the student will have a good feel for exactly how big of an angle π/3 or any of the other common units really is. That way the student will be able to use the unit circle to help them answer trig questions even when they draw their own unlabeled circle on scratch paper. After playing with the wedges the student should test themselves to make sure they have the right idea by clicking on the 'Test Yourself' button. Students can send their results to their teacher by clicking the 'Send' button on the results page. A larger version of this program is also available at Wisc-Online.
