Math 241: Calculus IV

0. Announcement(s)

All grades except final letter grades are posted on Blackboard.

I. Course Description

This course is Math 241, titled Calculus IV, as offered by the University of Pennsylvania for the Spring 2006 semester. According to the course register (slightly paraphrased), we will cover Sturm-Liouville problems; orthogonal functions; Fourier series; partial differential equations, including solutions of the wave, heat, and Laplace equations; Fourier transforms; an introduction to complex analysis; and (maybe) the use of symbolic manipulation and graphics software therefor. I will strike out topics in this paragraph that we've completed.

Math 240 (Calculus III) is a prerequisite.

Jeremy Magland is the professor for lecture section 002; I (TA Ben) am the TA for the corresponding recitation sections (211 through 214). Erik van Erp is the professor for lecture section 001 and Edward Crotty is the professor for lecture section 003; David Fithian and Armin Holschbach are the TAs for the corresponding recitation sections (201 through 204 and 221 through 224).

Our textbook is Advanced Engineering Mathematics (second edition), by Dennis G. Zill (of Loyola Marymount University) and Michael R. Cullen (deceased). Its ISBN is 0-7637-1065-2 (hardcover) or 0-7637-1357-0 (paperback); its LCCN is TA 330 .Z55 1999.

My students have lecture on Mondays, Wednesdays, and Fridays at 1 PM in DRL A5. My sections (211 through 214) meet in DRL 4E19 at 8:30 and 9:30 AM Tuesdays and Thursdays.

II. Coursework

A. Current Assignments

There is no homework left this semester.

B. Homework Policy

Homework is due promptly before 4 PM Fridays. Turn in homework either

  1. to me personally at recitation or office hours;
  2. under my personal office door if nobody's in my office;
  3. front and center on my personal office desk if somebody's in my office; or
  4. by special arrangement approved in advance by me (for example, you might need to email or fax me a homework if you are detained in another city).

Late or improperly submitted homework will never be accepted. Late or improperly submitted homework will never be accepted. Late or improperly submitted homework will never be accepted. If you know in advance you will be unable to turn in homework when it's due, you should plan to turn it in ahead of time. If you are unavoidably prevented from submitting homework for a good reason, you still may not turn it in late. I will drop your lowest two homework scores to allow for missed assignments or for assignments that pose especial difficulty.

Homework must be neat, well-organized, and legible. (Your name need be legible only if you want credit for the assignment.) Ragged margins, multi-column and otherwise over-dense formats, and unstapled sheets are unacceptable. If your handwriting is difficult to read (as mine can be), type your homework (as I do). If you tend to scratch out or erase incorrect parts of solutions (as I do), do a rough draft or type your homework (as I do). Write in paragraphs, sentences, and English words. Use punctuation and conjunctions to indicate your flow of thought rather than arrows or telepathy. Shoot for lucidity rather than terseness. Make the paragraph your unit of composition. I suggest reading The Elements of Style.

I will grade a few problems from each homework, and will give each homework a grade out of three points. Late homework, unstapled homework, homework with ragged edges, and illegible homework will merit a frowny-face. A timely, stapled, non-raggedy, legible submission without ragged edges that represents at least a sincere effort will merit a neutral-face no matter how incorrect or poorly written. A submission that is generally clear and correct will merit a smily-face. A submission that is perfectly clear and correct will merit a smily-face-with-the-teeth-showing. These four grades translate into 0, 1, 2, and 3 out of 3 points. I will post grades on Blackboard.

C. Quiz Policy

There will no quizzes.

D. Exam Policy

You should pose questions about exam policy to the professor, not to me, since exam policy is generally the province of the faculty. Also, make arrangements for alternate exam times through him, not through me.

I will post grades on Blackboard.

E. Final Course Grades

Dr. Magland will be allowed a certain number of A, B, C, and D/F grades to give based on the distribution of grades of his students on the exams, which you will take along with other students taking Math 241. Direct any requests for clarification to him. If he and I say different things about final course grades, he is right.

Because your class rank is a significant statistic in this grading scheme, I will post your percentile to Blackboard starting a few weeks into the course.

If you don't like your final grade, don't expect me to do anything about it, because the faculty are the only ones able to consider grade adjustments. (Also, even if I could change your grade, I almost certainly wouldn't; I'm a real hard-ass about such things.) Likewise, don't talk to me about incompletes. (My sincerest advice: Avoid incompletes at all cost.)

F. Academic Dishonesty

I will tolerate no cheating, plagiarism, or other forms of academic dishonesty. I will report cheating to the professor and, if we deem appropriate, to the Office of Student Conduct. See the Pennbook for the relevant University policy, and consult with me to clarify any ambiguities.

You may certainly discuss the course material with other students (I encourage you to do so), but when you sit down to write up your homework, do so alone.

III. Contact Information

You are welcome to email or call me any time, but if you have something that needs a response, talk to me in person (in class or in office hours) if possible. I can't guarantee I'll respond individually to all emails or to any phone messages.

Office hours
2-3 Monday and Thursday, or by appointment. I'll also be on AIM during regularly scheduled office hours. You may also stop by my office any time without an appointment, but I may be busy or out of the office, in which case you'll have to schedule a later time. When you want an appointment, bear in mind that I have obligations at the following times:
Monday
11-3;
Tuesday
8:30-1:30, 4-5:30;
Wednesday
4-5:30;
Thursday
8:30-3, 4:30-5:30;
Friday
11-1.
Office
DRL 4N27. This office may be hard to find (it's located on the so-called Hidden Hallway), so I will show the way to my office during the first week's recitations.
Phone
My office number is 215-573-6253, but I'm not usually in my office. I will give my cellphone number in the first recitation, and I'll give it to students again on request.
Email
schak at math dot upenn dot edu. (Please note I may only check my email once or twice a day, so don't use email for emergencies.)
AIM
BenTheMathTA. I'll rarely be on this account except during office hours.
Suggestions
I always want to hear your thoughts about the course. You can tell me your suggestions personally, you can email them to me, or you can write them down and put them in my mailbox in the department office.

IV. Help

Aside from office hours, there are many places to get help. The department offers math and Maple help (in person and online) four nights a week as well as weekly calculus review sessions. These are more under-utilized than the Swiss Army, and I highly recommend you take advantage of them. There are also residential math advisors (a program which may be moribund) and a Tutoring Center. Students with money to burn might consider private tutors---but be warned that most grad students charge extra for tutoring Math 241! (I estimate that current rates for 241 are between 40 and 60 dollars an hour.)
