ΚΠ

1844 Proc. Royal Irish Acad. 1840–4 2 496 When an axis of a cone which stands on a given base is always parallel to a given right line, the locus of the vertex is an equilateral hyperbola or a right line, according as the base is a central conic or a parabola.

1929 Amer. Math. Monthly 36 204 The theory developed for the central conics holds for the parabola if we make the customary modifications due to the fact that one focus of the parabola is at infinity.

2012 T. M. Apostol & M. A. Mnatsakanian New Horizons Geom. viii. 256 Focal circles for central conics can be used to give a simple treatment of a classical three-circle problem.
