    Solve for the steady state temperature distribution inside a cylinder of radius a for the following two cases
    1) Cylinder has height L, and T=0 at the bottom and at the walls, and T=100 at the top.
    2) Cylinder extends from z=0 to infinity, T=0 at walls, but T=rho sin(phi) at the bottom.
