So, can anyone think of a real-analytic simple closed convex planar curve as a candidate for the Simplest Oval ?
Try:
x^2=y*(1-y)*(1-y/2);
for 0<=y<=1 .
Or tinkering around with the parameters in a*x^2 = (b-y)*(c-y)*(d-y) improves this slightly, say a = 3, b = -1/2, c = 1, d = 2 ... Is this the earliest known example of a cubic egg? Fred Lunnon
