I have posted lecture notes from the last half of Thursday of last week through today here. Pp. 2--6 are mostly concerned with a more careful exposition of the derivation of the gradient and divergence in more general coordinate systems; since what we need for this course is mostly just the final expression for the Laplacian in spherical and cylindrical coordinates, these derivations can be skipped with no essential loss of continuity.

I have also made some adjustments to problems 4 and 5 on Homework 4. At least some attempt at both of these problems is (as usual) required for the assignment to be marked as `completed'.

(I have also added this assignment to Quercus so you can submit your solutions anytime. I apologise for my oversight in not doing this earlier.)

Dmitri will be in the math aid centre tomorrow from 11 to 1 as usual. If any of you have trouble making that time, or have any other concerns about office hours (mine or Dmitri's), please let me know.

It has also come to my attention that at least one of you has been trying to get help from TAs other than Dmitri at times other than the scheduled MAC hours for this course. I would ask that you not do this as it puts the burden for this course on TAs who have other responsibilities. Again, if you can't make the presently scheduled times, please let me know and I will try to work something out.

I am not yet certain when the term test will be held, or even how I am supposed to go about scheduling a time -- I am waiting for confirmation on this point and will let you know as soon as I know the time.

I had said I would post some sample problems yesterday evening but typing the lecture notes took quite a bit longer than anticipated -- I will post them sometime today (Friday). I apologise for the delay.

That's it for now -- best wishes on the homework, and see you all on Tuesday!
