heplane of yz parallel to that of the moving ellipse. LetOA = a be the common transverse semi-axis, and OB = h,OC = c, the two conjugate semi-axes. Let QPR be anyposition of the moving ellipse, J\IQ, MR its semi-axes, andP any point in it. Draw FN parallel to Q2I to meetRM in iV. OF THE SECOND… … These three surfaces, the ellipsoid, the hyperboloid of onesheet, and the hyperboloid of two sheets, are all included inhe equation Ax^ + By + Cz = 1. 39. The Elliptic Paraboloid. The elliptic paraboloid is generated by a parabola which.noves with its vertex in a fixed parabola, the planes of the…
