After the first week, I have not made substantial updates to Chang's file (admittedly, I have made none). However, I not only looked up numerous sources to properly learn Python OGL, but also made the changes you wanted to the Sine_Circle.html graph. Because the canvas defaults to 1600 x 900 psuedo pixels, I opted to make the canvas 800 x 450, 1/2 the original size. I then created a line that rotates around the center of the circle, in order to see more clearly which angle we are at and cleaned up the horizontal lines. It now looks and runs much smoother. For fun tonight, I plan to make it give an output of which angle you are at (between 0 and 2 * pi) and graphically represent it somehow.
