^mptotic cone. 4. Show that neither the ellipsoid nor the elliptic paraboloid has anasymptotic cone. 188. Projecting cylinders of a curve in space. The cylinderswhose generators intersect a given space-curve and are perpen- … dicular to one of the coordinate planes are called the projectingcylinders of the curve. Arts. 188, 189] PARAMETRIC EQUATIONS 245 To find the equations of the projecting cylinders, eliminate x,y, and z in turn from the equations of the curve. For example,consider the curve whose equations are…
