On Chords of a Conic which touch Another Conic

Abstract

A closed conic C is completely contained inside a closed conic S . From any point 1 on S we draw a tangent 1, 2 to C meeting S again at 2. From 2 we draw the tangent 2, 3 meeting S again at 3, and so on ; for any n , the tangent to C from the point n on S meets S again at n + 1.
