If you want to do more or other exercises than the ones provided in the weekly problem sets, you may want to check out last years exercises. There has also been published a solution manual for all these exercises:
Also, don’t forget about this week’s problem set.
The oblig has been posted on the course pages.
You can find it here under “Obligatoriske oppgaver”.
Please note that last weeks exercises included an oblig warm-up. This can be useful if you want to test yourself with a simpler problem before going ahead with the whole oblig.
In addition, you’ll find the note about Jacobi’s method on this page, under the link named “Numerical solutions of Laplace’s equation”.
You’ll find the due date in the oblig itself.
