(c) Solve the same equation again, this time using the implicit method given in Section 11.2.2 based on the backward Euler method. Again use A3: = 0.05, but try a much larger time step, say, At = 0.005 to advance the solution from t = 0 to t = 0.06. Plot the solution at each time step. How do the results compare with those in parts a and b? Explain. (d) Solve the same equation again, this time using the CrankNicolson method given in Section 11.2.2. Again use AI: = 0.05 and At = 0.005 to advance the solution from t = 0 to t = 0.06. Plot the solution at each time step. How do the results compare with your previous results? Explain
