2d - In addition solve with h=0.1 and give your solution in the form of a table with columns t and w(t)
4d - compare by plotting the actual error and the error bound on the same graph for both values of h
16 - In addition solve for t=0.01j, and plot the current vs. time

12.1
Problem 1: 3c, and verify order of convergence by calculating the rms error on at least 7 different grids.

Problem 2: Construct the system of finite difference equations (Ax=b) for the Poisson problem when the spacing in the x and y directions are not necessarily equal. Use second order central differences and Dirichlet boundary conditions.
