Reading

I'll probably ask you to read some of the sections in the textbook before most lectures, so we're in sync. I'll post the reading assignments here. Unless specified otherwise the sections are those in the textbook.

The date is that of the lecture, so please do the reading before that.

Supplementary material

On occasion I'll post extra notes, comments, etc. in this space.

Homework

We exchange homework via UBLearns: I post the assignments there through the 'Assignments' facility provided by the system and you'll similarly be able to upload files.

No late homework for any reason, but we are dropping the two lowest scores.

The grader will assign each homework a grade out of 10 with only a few problems being graded (3 or 4 or so). There will also be points awarded for the overall completeness of the assignment. I won't be telling you in advance which problems are being graded though..

Do collaborate on the homework if you like, but write up your own solutions. I also strongly advise you to have a look at the UB Academic Integrity Policy, as it very much applies to this class.

And by all means drop by at office hours if you need a hand.

Exams

We're having two take-home exams. The dates are as follows


Exam policy:

Those are the due dates. I will post the problem lists a few days before, so you will have plenty of time to work on them.

Grading

We'll drop the two lowest homework scores.
