Announcements:

Welcome to Math 371!
There was a misprint in problem 4 that has been corrected as of 10:15pm on Saturday.
As noted in the email, the final exam is now due on Monday Dec 16 at noon.
You talked me into it: Here is the final exam, due in my math department mailbox by Monday (the 16th) at noon.
Starting to think about the end of the semester. Next week (the week of the 9th), Brett will hold office hours in 3C13 on Monday (12-1) and Tuesday (4-5), and generally by appointment any time between now and the end of classes.

General Mathematics Undergraduate Information

General Information for this class:

Class meetings are TTh from 10:30 - 12:00 in DRL 3C8. The recitations are Wednesdays from 6:30-8:30pm, also in 3C8. Since there are so few of you, we have consolidated the recitations.

Since some of you took Math 370 last fall and others took it last spring, and you used different texts, we'll use Goodman's Algebra, which is downloadable for free. I'll also produce notes and extended problem sets from time to time.

My office is Cohen Hall 120 (the College office), tel. 8-7867, email deturck@math.upenn.edu. Office hours usually Mondays 7:00-8:30 pm. Since I live in Riepe College House in the Quad (in Magee 209), we might hold office hours there.

The teaching assistant for this course is Brett Frankel, his office is DRL 3C13, tel. 8-2949, email frankelb@...

Basic Ground Rules:

Homework will be assigned once a week or so, and due at lecture the following Thursday (so everyone gets a crack at recitation). The homework will often contain problems that are intended for you to present in recitation, so we can all practice civil mathematical discourse.

There will be two midterm exams, on Thursday October 3 and on Thursday, November 14. We'll talk about how these will work as the time comes closer. The final exam is scheduled for Friday December 13 from 9-11am.
