in three dimensions the equation 2 + y2 - 1 represents a Similarly, the equation y2+2 - 1 represents another cylinder. These cylinders have infinite and intersect at right angle. The set of all points that lie on or inside both cylinders is given in Figure The set of all such points can be characterized by the equations 2? + y2 <1 and -V1-y? Szs V1-y? The intersections of four and three cylinders are given in Figure and Figure Figure Each of the curves of the intersection of two cylinders is an . respectively. We can open the intersection as shown in Figure Figureb Figures Figured pyramid c cylindersphere alle d height Square 3 )
