Ellipse calculator formulas:

   Ellipse Foci F X Coordinate  =  x0 + √(a2 - b2)
   Ellipse Foci F Y Coordinate  =  y0
   Ellipse Focus F' X Coordinate  =  x0 - √(a2 - b2)
   Ellipse Focus F' Y Coordinate  =  y0
   Ellipse Eccentricity  =  √(a2 - b2) / a
   Distance from Center to Focus  =  √(a2 - b2)

   Area = PI * Semi-Major Axis * Semi-Minor Axis
   Circumference = PI * √(a2 + b2) * 2
