Does anyone know how the get the mathematic description to the curve of
an egg? I presume that the lower half of the egg is a half of a perfect
circle, but what about the rest?
Much to my surprise, the Handbook of Curves and Surfaces, published by
Chemical Rubber Co., did not have a mathematical equation describing an
egg -- the surface of rotation of the two dimensional figure called an
"oval". In addition, the comprehensive "Concise Encyclopedia of Mathematics"
edited by Eric W. Weisstein states that does not have "a precise
That came to me as quite a surprise.
