The equation of the cone z = Vx2 + y2 is given in cylindrical coordinates as z = r and in spherical coordinates as o= 1. Use cylindrical coordinates x = r cos 0, y = r sin 6, and z = z to give a parametrization of this cone.

2. Use spherical coordinates x = psin o cos 0, y = psin o sin 0, and z = pcos o to give a parametrization of this cone.
