On the equality of the convex hull of two circles with the union of certain family of ellipses
Abstract
In this article, we propose an alternative and elementary proof to a result proposed by the first two authors about the expression of certain convex hull of two cirles as the union of an uncountable family of ellipses. The tools employed include elementary calculus and analytic geometry. As a matter of fact, the tools employed allowed the proof of a slightly more general result than the original.
