What would the equation of that ellipse be?  It seems that it would be similar to the 1/2 radius circle................................................X squared + Y squared = 1/4..........is the equation for a circle.........centered at the origin.....................of a circle..........with a radius of 1/2................but an ellipse has one axis longer than other...........................so its equation would be different.....but only by a little bit.................from what I could figure..........it would be X squared + Y squared/3 = 1/4...........

X ^2/1 + Y^2/3 = 1/4.................................looks a lot like a garbled pi............and there is another type of 13..............................below X^ 2..........x squared.......is a one.....................same number, it is just written differently.................Y ^2..........y squared is over 3.............or 1/3 of Y^2.........= 1/4.......like 14i.........................a 1 a 3 and a 4..........................like the beg of pi........like 3 and 4........the 1st successive pair of numbers...........whose sum and products are more than one apart.................
