# The oblig is here

This post is from an earlier year, meaning the information here is likely outdated. You should look for a newer post from the current year to get the newest exercises and notes.

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.

You’ll find the due date in the oblig itself.

Good luck!

• Ja. Du kan velge selv, eller velge både numerisk og analytisk løsning, som sannsynligvis er det du lærer mest av.

1. Hi!

In part c of the oblig we are asked to use Jacobi’s method to find V(x,y) in the domain [0,a] X [0,b].

As i am reading this now, that is a line segment of length |a-b| on the y-axis. Is this correct or do you mean the domain [a,0] X [0,b]?

• Hi Knut,
the notation $[0,a]\times[0,b]$ means the rectangle with corners $(0,0)$, $(a,0)$, $(0,b)$, $(a,b)$. That is to say, the square bracket before the multiplication denotes the limits in $x$ and the square bracket after the multiplication holds the limits in $y$. This notation is quite common, so you are likely to see it again.

In fact, the domain $[a,0]\times[0,b]$ would be the same rectangle, although written in a non-standard way.
