Parametrize the curve obtained by intersecting the cylinder x + z 4 and the plane y = x. Make a single sketch showing both surfaces and their curve of intersection. Finally, find an equation of a second cylinder on which this curve lies. = Show that the curve with parametrization x = t sin 2t, y = t cos 2t, z = t for /2 t 2 lies on the cone z = x + y. Sketch the cone and the curve.
