Move your mouse, and see the triangle change according to the mouse pointer's position in the Unit Circle. This unit circle will give you the degrees of the angle, and the x/y (cos/sin) values of the angle according to the Unit Circle.
The Unit Circle is something we use in mathematics to see the relationship between Sin and Cosine (related to a triangle's sides in ration to the hypotenuse). I wanted to make this for my Pre-calculus teacher (for his Trigonometry classes). So, I guess this is dedicated to him. :-D If you want more information from the circle, comment and I'll see what I can do.
