Geometrical Conics Classic Reprint PDF Download

Excerpt from Geometrical Conics In the first chapter of the following work I have proved some of the properties of conics by methods which are applicable to all the different forms, and have then proceeded to consider the three types of conics in detail in separate chapters. The book may, however, be said to have two beginnings; for the chapter on the Parabola is so written that it may be read first by those who prefer this arrangement. In the first chapter I have made use of the Eccentric Circle of Boscovich to obtain a general proof of the fundamental theorem that the ratio of the rectangles contained by the segments of two chords of a conic drawn in fixed directions is constant. This method was first introduced into English text-books by Dr C. Taylor in his very able and comprehensive Treatise on the Ancient and Modem Geometry of Conics.
