In today's lecture: I derived ¡­

In today's lecture: I derived a finite difference scheme for the solutions of the Poisson's equation in one-dimension.

In next lecture: I will prove that the solution of this finite difference scheme converges to the solution of the Poisson's equation as the mesh is refined. I will also start with the solutions of the heat equation.

In the group lesson this friday: Prepare exercises 2.9, 2.12, 2.15, 2.16 and 2.17
