I will put copies of the Mathematica worksheets I prepare for class here.
Explicit finite diff. This worksheet illustrates the simple, explict finite difference approximation for solutions of the heat equation.
Implicit finite diff. This worksheet illustrates the implicit finite difference approximation for solutions of the heat equation that results from approximating the time derivative by the backward difference operator.
Wave equation. This worksheet illustrates the finite difference approximation for solutions of the wave equation.
