Mr. Unit circle

Mr. Unit circle is quite the handy device. It displays the four quadrants on a standard graph which already is a big help. Along with that it shows the measurements of the graph in degrees and radians. And with that it displays the sins and cosines with the standard right triangle lengths. The standard right triangles are of the following: 30-60-90 right triangles and 45-45-90 right triangles. 30-60-90 triangle have lengths of 1, sqr root of 3, and 2 and 45-45-90 triangles have lengths of 1, sqr root of 2, and another sqr root of 2.
