Example 2.  Solve  [Graphics:Images/FiniteDifferenceMod_gr_94.gif]  over  [Graphics:Images/FiniteDifferenceMod_gr_95.gif]  with  [Graphics:Images/FiniteDifferenceMod_gr_96.gif]  and  [Graphics:Images/FiniteDifferenceMod_gr_97.gif].
Use the finite difference method with 25 subintervals (total of 26 points).
Just use the subroutine and skip all the details.
