ab: A Descartes tangent line is defined to be a line which intersects the curve
    exactly once. The article investigates the following question: For an
    odd positive integer $n$, find a curve which has exactly $n$ Descartes
    tangent lines. The search is restricted to functions which are
    symmetric with respect to the origin, increasing and have Descartes
    tangent lines with zero slopes.
