I drew an oval using the ellipse tool of a vector-based drawing program. It's 23.5 mm wide and 21.5 mm high. There is a chord 15 mm long perpendicular to the minor axis. So the question is, how do I calculate the distance from the chord to the end of the ellipse (i.e., the end of the major axis).
(By the way, I've been wracking by brains trying to figure out an oval that's just a stretch-out circle could be a conic section. The best I can figure is a cone with an extremely small angle, cut diagonally many miles from the apex.)
