Basic course information

This section contains administrative information. See below for information on learning objectives, the syllabus, exams, homework, grading, academic conduct, course documents, and important dates.

Learning objectives

There are two primary goals of the course:

In somewhat greater detail (and including some things going beyond the list above), students successfully completing this course will be able to:

Weekly homework problems, as well as problems on the midterms and final exam, will provide students with opportunities to demonstrate the level of their abilities on the learning outcomes above.

Syllabus

This course will cover Chapter 8 of the textbook, plus additional material (references to be provided) on using power series to find solutions of suitable differential equations.

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 25 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. Note in particular that calculators and note cards are not allowed, that there is no partial credit, and that 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. No calculators or other electronic devices will be permitted on any exam. In particular, no electronic dictionaries will be permitted on any exam. Exams will permit a 3 by 5 file card, written on both sides, readable without a magnifying glass.

At least 80% of the points on each of Midterms 1 and 2 will be based on homework problems, on problems on separate supplementary lists (including sample exams), and on problems from all versions of Midterm 0. (I don't know about the final: I have much less say about exactly what is on it.) 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) = 2x^{-4}, g(x) = 2x^3, or f(t) = 2t^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.

Miscellaneous

Canvas will not be used. You should keep track of your own scores.

Homework

Homework will be written. (No WeBWorK. It can't grade your explanation of why an infinite series does or doesn't converge.) Assignments will be turned in to me at the beginning of the class period in which they are due. 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. Here, you will unfortunately see the disadvantage of not using WeBWorK: many problems will not actually get graded. 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.
  1. Week 1 homework and solutions.
  2. Week 2 homework and solutions.
  3. Week 3 homework and solutions.
  4. Week 4 homework and solutions.
  5. Week 5 homework and solutions.
  6. Week 6 homework and solutions.
  7. Week 7 homework and solutions.
  8. Week 8 homework and solutions.
  9. Week 9 homework and solutions.
  10. Week 10 homework and solutions.

Advantages of WeBWorK (unfortunately lost for this class):

Disadvantages of WeBWorK:

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.

Extra credit

There will probably be extra credit problems on the midterms and final exam.

I will also 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. 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, and if it is on something on the website you must point it out to me (perhaps by email) before I find and fix it myself.

There will also 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 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 bring any unauthorized material to exams. (Exams will permit a 3 by 5 file card, written on both sides, readable without a magnifying glass.)

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.
