Announcement about the week of Oct 26

I mentioned in class that I'll be away during that entire week. That means no class on Monday Oct 26 or Friday Oct 30.

The midterm is scheduled for Wednesday Oct 28, during that week; please show up at the usual time and place, where a substitute will administer the test.

We're using the 3rd edition of Walter Rudin's Principles of Mathematical Analysis. The textbook is absolutely necessary, both for the reading and in order to do the assignments. We'll be covering the first 4 chapters.

It's essential that you do the reading. I won't have time to go over every relevant example in class, and you'll need a good grasp of the material in order to do the homework. In fact, I encourage you to regard the reading as part of your homework.

Supplementary material

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

I will post homework assignments in the table below. It'll be due weekly on Wednesday, in class. I might post solutions to selected problems, but certainly not to all of them.

No late homework for any reason, but I will drop the lowest score.

Because of time constraints your TA will grade a couple of problems (tops) for correctness and the rest for completeness. I won't be telling you in advance which problems are graded for correctness though..

It's happening in class (usual time and place) on Wednesday, October 28 (see the announcement at the top of this page for the schedule for that week). The material is what your first three homework assignments cover: everything up to and including the 'Compact Spaces' section of Chapter 2.

Your homework is good training for the test; it will consist of probably a couple of proofs similar in nature and difficulty to the problems on your first three homework sets.

Both the midterm and the final are completely open book. You can bring anything you want to the exam (textbook, class notes, your own past homework, etc.).

Pre-midterm office hours: There are some by myself and some by our TA, Zihui Zhao.

The test, with solutions.


It's been set by the department, and I have no control over time and location. I can't offer you an early / late exam, so if you can't make it you should switch to the other 424 section.

The exam will be

As I said above, the exams are both open book.

As mentioned above, we'll drop the lowest homework score.

"Overloading" means allowing more students in class than the limit (which in our case is 40). Because 40 is also our room limit, there will be no overloading.
Disability Resources

If you need special accomodations please go to DRS (Disability Resources for Students) for more information. You should meet with a DRS counselor and get a letter attesting your need for academic accomodations. Once you have such a letter, please see me so that we can arrange for those.
