1. +y coordinate as a, +x as b, C is the found by pythagorean, we need to make C a curve so we have in quadrant 1 three x coordinates and 3 y coordinates, x1 = 2C/pi, y1=C/pi, x2 & y2 = (x1+y1)/2, x3=y1, y3=x1. Of course quadrant 3 is all negatives, quadrant 2 x are positive and y are negative, quadrant 4 y is pos x is neg   (Did the math on that it works to make a perfect circle)   2. a 45 degree angle or C can be found by starting at the top corner of quadrant 4 and bot
