Here you find a solution for the exam. It was prepared rather quickly, so there may be typos. Let me know if you spot any, and I'll revise the solution. Correcting the exams will take three weeks max, hopefully less.

On Thursday May 11th, instead of the usual lecture (14-16), there will be a problem session in Origo. You are encouraged to work on PS13 (Partial differential equations). Unless there are many people needing help at the end, the usual problem session 16-18 is then cancelled.

There will also be problem sessions at the usual times for PS13 the following week, so last time on May 18th.

Here is a solution of problems 1 and 2 of the home exam. Problem 3 will follow as soon as possible (next week). I apologise for the delay!

As we are approaching the last problem set, I encourage you to check that you have passed sufficiently many problem sets to be allowed for the final exam. Remember: You need a "pass" in at least 6 of the 12 first problem sets. Problem set 13 will not be for handing in (but equally important nevertheless).

... have been posted on the web page. A solution will follow soon.

The results of the home exam, and a solution, will hopefully be posted within a week after Easter.

The LHS of Eq.(93) should be y'' + y, not y'' + y'

Thanks to Markus for pointing this out :)

Unfortunately we have to cancel Thursday's lecture as well. 

Please study yourselves the first part of section 3.4 in my lecture note (3.4.1) on series expansion methods. Read sec. 12.1 and 12.2 in Boas carefully. Attend the problem session tomorrow if possible, ask there if there are things you don't understand. Discuss among yourselves.

The next problem set will be about the self-study material of this week, and I will pick up starting with the Frobenius method next week.

Regrettably the lecture on Wed March 29 is cancelled due to illness. Since the lectures on ordinary differential equations are extremely similar to my lecture note, please use the time to carefully study the material on Green's functions (section 3.3) yourself! The weekly summary slides are also available on the web page.

Hope to be back on Thursday :)

There is now a brief note on Dirac delta functions, covering the material lectured last Thursday. Some problems on delta functions are included in your next problem set.

You can now find the home exam on the usual page for weekly problems, or here -- good luck and enjoy!

The answer to problem 10.4.6. in Boas is wrong; the y and z coordinates in that answer should switch roles.

The home exam will be made available Friday March 17, and the deadline will be the MORNING of Monday March 27.

 

PLEASE NOTE: The extra time is provided to give you flexibility to divide your time with respect to other midterm exams. The workload will NOT be so big that you should spend ten days on this home exam. It should be possible to do it in 2-3 days.

 

ALSO NOTE: We are not using Devilry for the home exam. You will have to hand in a printed copy at the front office. Instructions will be given on the problem sheet.

One 3rd year student (Martine Ruud) has volunteered for the course evaluation/contact group. I need at least one more, preferably a 4th semester student. Contact information for the student representatives will be posted here.

(One person did volunteer at a lecture but never got back to me on email.)

There will be no lecture Thursday next week, Feb 9th. Everything else will be as usual.

As some of you have noticed, Devilry is now up and running. This means the deadline for problem set 2 is the original one, Friday 3rd (before midnight). You should also hand in problem set 1 now, by the same deadline. From now on the weekly deadline will be Friday as planned.

PS2 is out now.

We will use Devilry for electronic hand-in of weekly problems. However, IT cannot set up the database until after the final registration deadline for the course (Feb 1st). This means we will extend the deadline for problem set 1 until Devilry is functional. Stand by for further notice :)

As the course is being taught in English, the problem sets (including home exam) will be in English only. But you are always free to write your answers in Norwegian! For the same reason, we plan to have the problems for the final exam in English only. Any strong objections against English exam problems must be raised before Feb 1st, by contacting the lecturer (S. Viefers).
