Syllabus

This course will cover most of Chapters 5--7 of the textbook. Chapters 1--4 will be assumed to be known.

The following is an approximate schedule. Adjustments may be made as we go through the quarter.

Exam and review session schedule

Exam policies for Midterm 0

It will be review; only 20 minutes long. For those who know the material of the prerequisites, it should be an easy way to start the quarter with a high grade. See the sample (together with other information) (assigned as homework in the first week of classes), and read its instructions. In particular, calculators and note cards are not allowed, there is no partial credit, and it is graded on an absolute scale.

Complaints about the grading of any exam must be submitted in writing by the beginning of the first class period after the class in which that exam is returned.

Items (4) (answers must be simplified) and (6) (use correct notation) of the general instructions for written homework also apply to Midterm 0.

Exam policies for all exams except Midterm 0

All exams are cumulative, although they will usually emphasize the most recent material. All exams will cover material through the most recently turned in homework. All exams will be open book, and will allow calculators. No interactive help will be allowed. This applies to in person help or internet based help, including but not limited to internet searches, the posting of problems to or reading solutions from any website, etc.

At least 80% of the points on each of Midterms 1 and 2, and the final exam, will be based on homework problems (both written and WeBWorK), on problems on separate supplementary lists (including sample exams), and on problems from all versions of Midterm 0. Written homework will contain problems of types which are good for exams but do not appear in WeBWorK. Note that numbers may be changed in these problems. Similarly variable names, function names, and names of people etc. in word problems may be changed. Thus, f (x) = 2x^3 could become any of f (x) = -4 x^3, f (x) = 2 x^{-4}, g (x) = 2 x^3, or f (t) = 2 t^3. Such changes might turn a local maximum into a local minimum or result in other such reversals.

Complaints about the grading of any exam must be submitted in writing by the beginning of the first class period after the class in which that exam is returned.

Except where obviously inapplicable (such as in the parts about working with other people, or where explicitly contradicted by exam instructions), the general instructions for written homework also apply to exams.

Homework

There will be two kinds of homework. Quick links: WeBWorK; list containing links to written homework (and other documents).

Written homework

Written homework will be submitted via Canvas, usually Friday evenings. Links to them are in the list of publicly available documents associated with this course. Most of them will probably be graded by a homework grader. Read the separate Instructions for written homework (pdf); here is a brief summary of the most important points: Here is a list of links for homework assignments. They won't work until the relevant assignment is posted; the links here will only be posted when they are working.
  1. Week 1 homework, solutions, and other information (such as exams).
  2. Week 2 homework, solutions, and other information (such as exams).
  3. Week 3 homework, solutions, and other information (such as exams).
  4. Week 4 homework, solutions, and other information (such as exams).
  5. Week 5 homework, solutions, and other information (such as exams).
  6. Week 6 homework, solutions, and other information (such as exams).
  7. Week 7 homework, solutions, and other information (such as exams).
  8. Week 8 homework, solutions, and other information (such as exams).
  9. Week 9 homework, solutions, and other information (such as exams).
  10. Week 10 homework, solutions, and other information (such as exams).

WeBWorK

Assignments using WeBWorK will be done on the internet, here. Your WeBWorK account name is your UO email account name (without the "@uoregon.edu" part), and your password is the one you use for things like University of Oregon email. Thus, if your UO email address is "lqwang@uoregon.edu" and your password is "IHateSpam", your WeBWorK account name will be "lqwang" and your password will be "IHateSpam".

Due dates for WeBWorK assignments are as specified online, and the day of the week will vary.

The login page will fail with no explanation if cookies are off, and WeBWorK will fail if JavaScript is off. (To protect privacy, I advise deleting all cookies after you are done, for this site or anywhere else. I also advise turning JavaScript off when you leave the site.) The WeBWorK home page has links to all Winter 2021 UO courses using WeBWorK, and login instructions.

Warning: In the past there have sometimes been problems with the WeBWorK server. Most such problems are fairly minor: it is down for a few hours or overnight. Occasionally there have been much more serious problems, for example, no access for a week, completed homework lost, etc. Most quarters, nothing like this happens.

Grading

Grading percentages

Grading percentages:

Course grade limited by final exam grade

The course grade will not be more than one letter grade above the final exam grade. For this purpose, scores more than one grade interval below the D/F cutoff will be considered to be "F-", and limit the final course grade to F. In particular, not taking the final exam means an F in the course, even with perfect scores on everything else.

Extra credit

There will probably be extra credit problems on the midterms (except Midterm 0) and on the final exam. They will only be counted if you get a grade of 75% or better on the main part of the exam.

I will award extra credit points to the first two people who catch any particular error or misprint in the book or in any of the handouts, in particular, in solutions to midterms, homework, etc., as well as on web pages etc. (this includes broken links). The largest amount of extra credit is given for catching mathematical mistakes. You must point out exactly where the mistake is, and how it should be fixed.

There will be extra credit for getting perfect scores on both administrations of Midterm Zero.

Extra credit will count toward the grade only for those who consistently do the homework reasonably, and only for those whose grade in the course would be at least a B- without it.

Academic conduct

The code of student conduct and community standards is here. In this course, it is appropriate to help each other on homework as long as the work you are submitting is your own and you understand it, and, on written homework, you give the names of any people you cooperated with. It is not appropriate to help each other on exams, to look at other students' exams, or to use unauthorized material on exams.

Publicly available documents associated with this course

Here is a list of publicly available documents associated with this course. The material is arranged in approximate chronological order: most recent items at the bottom. Links to written homework solutions, exams, and exam solutions will not work until after the corresponding written homework has been turned in or the corresponding exam has been given, and the links to sample exams and their solutions will not work until these items have been prepared.

Most files will be pdf.
