OverviewIn the present Treatise the Conic Sections are defined with reference to a focus and directrix, and I have endeavored to place before the student the most important properties of those curves, deduced, as closely as possible, from the definition.The construction which is given in the first Chapter for the determination of points in a conic section possesses several advantages; in particular, it leads at once to the constancy of the ratio of the square on the ordinate to the rectangle under its distances from the vertices; and, again, in the case of the hyperbola, the directions of the asymptotic follow immediately from the construction. In several cases the methods employed are the same as those of Wallace, in the Treatise on Conic Sections, published in the Encyclopedia Metropolitan.
