(a) (i) Write down the finite difference equation corresponding to the three-dimensional partial differential equatioin d²ud²u d²u + + +u+xyz = 0 дх2 дуг дz2 at the grid point (x, yj, zk) of a rectangular mesh with Ax = Ay=Az = h. Denote u (xi, yj, zk) by Ui,j,k. (ii) Re-write the difference equation in (i) into an iteration formula appropriate for Liebmann's method. Use the superscripts uk, uk+1 to show how new values are computed from previous ones.
