In the lecture today: Trygve ¡­

In the lecture today: Trygve described an explicit finite difference scheme for the wave equation and showed that it is stable by using the Von-Neumann stability analysis.

In the group lesson this friday: Prepare exercises 5.9 and 5.11

Next lecture: I will describe a non-linear PDE that models population growth. The underlying ODE will be analysed and a finite difference scheme to approximate solutions will be designed. The material will be from chapter 11 of the book.
