Crunode (Cartesian coordinates)

Description

In mathematics, a crunode (archaic) or node is a point where a curve intersects itself so that both branches of the curve have distinct tangent lines at the point of intersection. A crunode is also known as an ordinary double point. A conchoid of de Sluze curve with an asymptote x=1 (for a≠0) and for a<−1 is a crunode. A crunode at the origin of the curve is defined by the above equation.
