Syllabus for Math 32, Spring 2001

Instructor: Tracy Hall
Discussion leaders: Sarah Carr, Elizabeth Cepeda

Required Materials

Text: Precalculus, David Cohen, fifth edition

A calculator is recommended but not required. No calculators will be used during examinations.


Grading Policy

I will try to give grades which reflect your mastery of the material as follows:

   A, A-: Complete mastery of all subject matter, and the ability to reason effectively and communicate clearly in applying these principles to novel situations.
   B+, B, B-: Complete understanding of all subject matter, and ability to apply it in familiar contexts.
   C+, C, C-: Partial understanding of all the subject matter, or complete understanding of most but not all of the subject matter.
   D+, D, D-: Partial understanding of most of the subject matter.

You are not competing with each other; if every student shows that he or she has learned all of the material, then I will feel fully justified in giving all A's and B's.

You will receive scores for the various assignments and examinations, which will be weighted as follows:

10%
homework
10% quizzes
15% midterm I
15% midterm II
10% research paper
40% final examination

Your raw score when these numbers are added will determine your grade as follows:

91-100%: A-, A
81-90%: B-, B, B+
71-80%: C-, C, C+
61-70%: D-, D, D+

These grades are a guaranteed minimum. If I later decide that the class as a whole has demonstrated better mastery of the subject than is reflected in the raw scores, I may adjust the grading scale in a way which slightly improves the final grades.

Participation

Reading Ahead

Our text this semester is Precalculus, by David Cohen, fifth edition. You are expected to read each section of the textbook before the corresponding lecture, according to the
schedule below.

Your preparation for lecture does affect your grade, even if only indirectly. We have a great amount of material to cover in a short amount of time, and it will be very hard to follow if you are hearing it for the first time. In fact, there will be some things I will not have time to discuss at all. Unlike in high school, you will still be tested on all of the assigned reading whether I have covered it myself or not.

From time to time we may ask you to record how consistent you have been in your reading. This will not affect your grade directly, but it gives you a chance to be accountable for your own preparation and gives us an idea of how effective we have been in encouraging you.

Attending Lecture

Lectures will take place from 8:10 to 9:00 am every Monday, Wednesday, and Friday in room 9 of Lewis Hall, except on holidays as noted in the schedule. Attendance is required but not recorded. You are responsible for knowing all material covered in lecture, whether or not it is part of the textbook or the assigned homework (unless I specifically tell you that I'm going off on a tangent which is outside the required material). I will attempt to be more or less consistent with the material covered and notation used in the text, but in case of any conflict, the lectures are your primary source of information.

Attending Section

Attendance is also required in discussion sections. It will not be recorded directly, but will be reflected in quizzes and homework.

Office Hours

My office hours for the semester will be as follows: Monday 9:10-9:30, Tuesday 1:10-1:30, Wednesday 11:10-11:30, Thursday 11:40-12:00, and Friday 9:10-9:30, in my office, 1008 Evans. I will try answer questions for any students who arrive during these times, which means that some days I will stay for longer than 20 minutes, especially during Weeks 3 and 4, when you will each need to come in so I can help you find a topic for your research paper. I am also available by appointment.

Sarah Carr's office hours are 11:10-12:00 and 1:10-2:00 on Tuesdays and Thursdays and 12:10 to 1:00 on Wednesdays, in 854 Evans. Elizabeth Cepeda holds office hours from 9:10 to 10:00 in 1015 Evans on Tuesdays, and from 3:10 to 4:00 in 862 Evans on Wednesdays.

Study Groups

You are encouraged to work together in groups outside of class. You can never be sure that you really understand a principle until you are able to explain it to your classmates; in addition, the more people you hear explanations from the more likely it is that you will hear something that finally "clicks".

Although I expect each of you to work each homework problem and hand in your own work, it is entirely appropriate for you to work with other people in trying to understand the right approach to a problem. Go ahead and work the problems together, or have someone explain the problem to you, but everything you actually hand in should be your own work.

You get imaginary bonus points every time you find yourself saying, "Not then, that's when my Math 32 study group meets."


Homework

Homework will be assigned three times a week in lecture, and collected twice a week at the beginning of your discussion section. It will be due at the next discussion section after it is assigned, but not actually collected until the beginning of the section after that. For example, the lecture on Friday of Week 3 will cover sections 3.3 and 3.4 of the text, and Homework #6 covering those sections will be assigned on that day. Homework #6 will be due the next section, which is Tuesday of Week 4, but will not be collected until the beginning of section on Thursday of Week 4. This gives you a chance to ask questions about homework questions that turn out to be particulary difficult for you, but it also leaves you no excuse not to have the homework ready when it is actually collected.

The homework will be graded by an outside reader who is hired just for that purpose. In addition to your name, "Math 32", and your section number on the front of each assignment, please also list which homework assignment it is (HW #1, HW #2, etc.) so that it can be easily sorted out if it gets into the wrong stack. It's a good idea to have your name at the top of every page, and please staple all the pages of an assignment together. When you are turning in two assignments on the same day, turn them in separately.

It will be impossible for the reader to comment on every single problem. Typically some credit will be given just for having completed every problem, showing all your work rather than just an answer, and then one or two of the more difficult problems will be graded in more detail. As a result, it is possible to do 90% of the problems and still only get half credit, if the problems you skipped turn out to be the ones which are graded. Homework accounts for 10% of your grade.

Homework may be turned in before it is officially collected with no penalty. Late homework is not graded. To make allowance for the emergencies which will inevitably arise, the lowest two homework scores will be dropped (but remember that you will typically be turning in two assignments on Thursdays). It is to your advantage to reserve this allowance for genuine (unpredictable) emergencies, and to turn your homework in early when you are aware of a possible conflict.

Extra Credit

Your discussion leaders may occasionally elect to give you "bonus problems" to work on. These will typically be problems which are especially difficult, or problems whose solution gives additional insight to a current topic. These will not actually count for any points, but a record of good work on these problems gives us some leeway in deciding borderline grades. These should be turned in separately from your other homework; they won't mean anything at all to the reader.
 

Quizzes

There will be one quiz given each week, in the Tuesday discussion section. It will normally cover the same material as the homework which was collected that day or the previous Thursday; thus the subject of Tuesday's quiz in Week 5 will be the lectures and reading of Friday, Week 3; Monday, Week 4; and Wednesday, Week 4.

There will not be a chance to make up missed quizzes; instead, the lowest score will be dropped. Again, it is far preferable to use this provision for a genuine emergency. Altogether, quizzes account for 10% of your grade.


Midterms

Midterm I will be held on Friday, 2 March, at 8:00 am sharp. No calculators, notes, or other references are allowed. It will cover all of chapters 3, 4, and 5, except for section 4.3, which is not part of this course. In addition, chapters 1 and 2 are expected background material.

Midterm II will be held on Friday, 13 April, at 8:00 am sharp. No calculators, notes, or other references are allowed. It will cover chapters 6, 7, and 8, and also sections 12.1 and 13.6.

Note that class will start 10 minutes earlier than usual on these two days, so the exam will last 60 minutes rather than 50. This gives you more time to be careful in your answers, while still allowing us to cover the required material. It's not a bad idea to arrive even earlier than 8:00 on those days, so that you can start the exam feeling relaxed rather than hurried. Make sure to get to bed in plenty of time both the Thursday and the Wednesday before these important exams, which together account for 30% of your grade.


Research Paper

No amount of problem-solving ability will be of much use to you if you are not able to communicate your results; this ability is explicitly part of what I am looking for in my
grading policy. I am also hoping to improve your enthusiasm for mathematics by exploring some connection between mathematics and the things you are already interested in.

The subject of your paper is mostly up to you, although I will try to provide some suggestions to get you started. Your writing should show evidence of the following things:

I anticipate that it will take at least 5-6 double-spaced pages to accomplish these goals.

The research paper is worth 10% of your grade. It will be graded out of 100 possible points, broken down into four sub-assignments. We will start off with an

(10 points) initial consultation, which means little more than showing up for my office hours during the first few weeks of class, introducing yourself, and chatting. We will try to find the interesting mathematics which may be hiding in some of your favorite subjects. In a broad sense, mathematics is just the attempt to recover additional information from limited data, or to see a deeper structure arising from limited assumptions. That leaves a lot of room for discovering mathematics in places you may not have expected. Based on our conversation, your own musings, and possibly input from other sources which you will seek out yourself, you will write a one-page

(10 points) research proposal detailing exactly what it is you hope to find out. The proposal is due on Friday, 16 February, so try to come in for the initial consultation as soon as possible. Your favorite professors in other subjects are also an excellent source of ideas for your proposal, as are people who are already working in your chosen career or who are skillful or advanced in one of your hobbies. In fact, this writing assignment should serve as a good excuse to get to know people who may someday be writing letters of recommendation for you. Once your proposal is approved, you will then carry out the actual research and write the

(20 points) paper itself, or technically a first draft of the paper, but one which will be graded on its own merits. The paper will be collected in lecture on Wednesday, 21 March. I am a stickler on all points of style, grammar, spelling, logical flow, etc., and you will want to finish all of your research and write a complete paper the first time around. That gives us a chance to catch as many problems as possible at this stage rather than in the

(60 points) final draft, which will be collected in lecture on Friday, 27 April. It will be easier to gain a sense of exactly what I expect if you produce your best work the first time around.

As the various deadlines approach, there may be handouts explaining the assignments in further detail.


Final Examination

The final examination is scheduled for Friday, 11 May, at 8:00 am. No calculators, notes, or other references are allowed. Like the midterms, this exam will start promptly on the hour. We will not know the room or building until later in the semester.

The final will be comprehensive, but with slightly more emphasis on material which was not covered by either midterm (such as sections 12.2-12.6 and 13.1-13.5). It counts for 40% of your final grade.
