Given: The equation of the cone z = va2 + y2 is given in cylindrical coordinates as z = r and in spherical coordinates as o = 4 1. Use cylindrical coordinates x = rcos, y = rsin 0, and z = z to give a parametrization of this cone. 2. Use spherical coordinates x = psin o cos, y = psin osin 0, and z = p coso to give a parametrization of this cone
