Interactive Unit Circle

UPDATE: Model works conceptually, but not practically. DO NOT PRINT.

This tool is a fun way to learn and teach about the unit circle. The Interactive Unit Circle can be operated by turning the pointer to any value between 0 to 2π (0° to 360°), the cosine and sine arms will indicate the value of cosine and sine at the set angle measure. This tool provides the user with an interactive experience to quickly learn the many values of cosine and sine. It may be used in trigonometry settings or even higher division mathematics for students who struggle with the unit circle.
CAUTION: This design is a work in progress, and requires further testing. If there are any suggestions or issues, do not hesitate to comment and I will do my best to accommodate.

UPDATE (1): Scaling issue solved, no conversion ratios necessary.
