General Information

The lectures take place in Towne Building 100 on Tuesdays and Thursdays between noon and 1:30p.m. and are held by Prof. Ziller. There is a weekly homework assignment and a 5min weekly quiz, which will be taken at the end of recitation. There are two midterm exams (February 19th and April 8th) and a final exam (May 9th). The exams, the quizzes, the homework assignments and participation in the recitations contribute to your final course grade (see below).

Email

I will send out general organizational information by email, so make sure you check your inbox at least once a week (shouldn't be hard!).

You can ask about anything you want, I will reserve the right to ask you to come to office hours, or address the question in the next recitation. In particular, I will NOT answer mathematical questions by email, so don't bother asking. This does not mean that I do not want to answer them, I will be happy to, just not by email. Also, questions about the exam should be directed at Prof. Ziller, not at me.

Religious Holidays

We are not allowed to have homework due or test scheduled on a religious holiday. Let me know within the first two weeks of class if any of your religious holidays coincides with a due date for the homework asignments, and I will reassign it for a later date. Quizzes scheduled for a religious holiday will either be cancelled (for all recitations) or rescheduled for the following week.

Tests

Quizzes: There will be a 5min weekly quiz taking place at the end of recitation. It is based on a problem from a previous homework set. It will be returned the next recitation. The quizzes will be graded on a five point scale for mathematical correctness. One point is given for the completely unacceptable solution and five points are given for an essentially completely correct solution. If you miss a quiz (see 'makeups' below) you will get zero points.

Midterm exams: There will be two midterm exams spaced throughout the semester. The tests will be written by Prof. Ziller. Any questions about the exams should be directed at Prof. Ziller.

Final Exam: The final course exam takes place May 9th and is written by a committee of Math 240 professors. The same exam is given to all sections of Math 240 at the same time during finals week.

Homework

Deadline

Homework is due Friday at 4p.m. You put it in my mail box in the mathematics office (4W1). If extraordinary circumstances make it impossible for you to hand in the homework in person, you can email it to me if this has been agreed on by me beforehand. No late homework is accepted for any reason.

Grading

The homework is graded for completeness. I will use a 0 - 2pt scale. If you don't hand in a solution, or if it is essentially totally incomplete I will give 0pt. An assignment where about half of the problems are done recieves 1pt and I will give 2pts for an essentially complete solution to the assignment.

Group Work

Working with other people on mathematics is not only allowable, but is highly encouraged and fun. You may work with anyone (other students in your section, in the course, not in the course, bums on the street) on your homework problems. If done right, you'll learn the material better and more efficiently working in groups.

The golden rule is:
You may work with anyone on solving your homework problems, but you must write up your final draft by yourself.

Writing up the final draft is as important a process as figuring out the problems on scratch paper with your friends. Mathematical writing is very idiosyncratic - I will be able to tell if papers have been copied - just don't do it! You will not learn by copying solutions from others! Also, if you work with people on a particular assignment, please list your collaborators somewhere on the top of the paper. Make the process fun, transparent, and honest.

Presentation

Homework must be stapled, with your name and recitation number clearly written on the top. Consider the pieces of paper you turn in as a final copy: written neatly and straight across the page, on clean paper, with nice margins and lots of space, and well organized. If I can't read it, I won't grade it. If it looks like scratch paper, I will dock points. On the other hand, I highly recommend that you get into the habit of working out all your solutions on scratch paper, and then writing up your final copy. This way you can avoid erasing whole pages. If your handwriting is illegible, then type up your papers, as you would for your English class. Write in paragraphs, complete sentences, and English words (you may also write in German and Danish, if this if more convenient for you), complete with punctuation and transitional words and phrases to clearly delineate your argument and flow of idea. Mathematical writing has its own style, so notice how the textbook presents worked examples and how I present solutions in recitations. Strive for clarity.

Grade breakdown

Percentage Table:

Midterm 1: 20%

Midterm 2: 20%

Final exam: 40%

Homework and quizzes = 20%.

Grades will be posted on Blackboard.

Your final course grade is based on the percentage table above. Notice that although exams make up 80% of your final course grade, completing your homework on a weekly basis is the most sure way to success on tests and hence to get good final grade.

Because of the certainty of your alarm failing to wake you up, illness, family emergencies, or just plain hang-overs during the semester, let me emphasize this now to spare you the confusion and frustration later. I will drop your lowest quiz and homework score when calculating your final homework and quiz grade. I hope this is a fair way to compensate for an inflexible policy.

Makeups

Midterms: If you know you are going to miss a midterm exam, plese let Prof. Ziller know as soon as possible (office hours or email).

Quizzes: There are no makeup quizzes. If you are ill or have other personal isues preventing you from taking the quiz in recitation let me know as soon as possible. Your college advisor must confirm the issue by email. We will then schedule the quiz for a later date, most likely for a later office hour (The question will be different, so you get no advantage by missing a quiz). There will be NO makeup of missed quizzes where I haven't been notified in advance. This is not negotiable!

Homework: I do not accept late homework, where 'late' is defined as after the deadline (Friday at 4p.m.). Religious obligations, illness, and family emergencies are not excuses.

Final: There is the possibility of a makeup final exam, but don't waste your break worrying about that! You must warn Prof. Ziller well ahead of time if you must miss the final exam.

Help Resources

It is important that you understand that our only objective is to help you understand the material better. Period. So, if you have problems, for example if you are falling behind with homework, if you have difficulties understanding what is presented in the lectures or maybe you are simply getting worn down because of the general work load, there are several things you can and should do.

(1) Email me or come see me and tell me about your problems. If I can't help you with your problems, I know of somebody who can!

(2) Go to Math/Maple center and seek help. This is an excellent way of getting help with the homework or problems you have encountered while reading the textbook.

(3) You can get online help here. Experienced TAs are available to answer questions by email every night from 9p.m. to 1a.m.

(4) Go to the Sunday review. It is an excellent opportunity to ask any course related question you may have. It takes place every Sunday from 7p.m. to 9p.m. in DRL A6.

(5) Private tutoring is an excellent way to get rid of small (or big) misunderstandings. You pay an experienced graduate student (pick one from the 'approved by the department' tutor list here to teach you the fundamentals, to help you with the problems, or whatever way you would like it. You pay for it, the average salary is 40$ an hour; I am not allowed to tutor Math 240 students.

Enjoy the Course and Good Luck!
