Unformatted text preview: P is any non-horizontal plane not containing A , and let be the intersection of P with K . Rotating our picture about the axis if necessary, we can assume that P intersects any horizontal plane in a line parallel to the x-axis. The yz-plane intersects P in a line that meets in one or two points; we label the rst P and the second (if it exists) P ; these are the vertices of (Figure 2.3 ). Given a point Q on distinct from the vertices, let H be the horizontal plane through Q , and dene the points R , V , B and C as in Figure 2.2 . The line segments QV and PV are, respectively, the ordinate and abcissa ....
