1.Using the Crank–Nicolson time approximation scheme.
2.Derive the global system of equations in chapter13 using the explicit time approximation scheme. Estimate the largest tlargest based on Eq. Solve the global system of equations using time step t5tlargest for temperature distribution and heat transfer rates. Plot the heat transfer rate at the right surface as function of time.
3.Derive the global system of equations in using the quadratic line element.
