Additional information: You can find additional information on the following website additional info. In particular, there are practice exams and their solutions, as well as lecture notes (in pdf format) in the section "Schedule and summary of lectures (tentative)" (click on the section numbers). These notes are from a course by another instructor, but might still be useful.

Homework assignments

Homeworks need to be turned in on or before the stated date, usually a Friday. No homework needs to be turned in on Fridays when a midterm is scheduled. However, some of the homework may also be part of the material being asked for the midterm. It is very important that you do the homework problems as most of the exam problems will be variations of homework problems.

Disclaimer: I will try to get the homework assignment on the net in time. Due to time and other limitations, this may not always be possible. The fact that there is no assignment posted for a particular date does therefore NOT necessarily mean that no homework is due.

Information for final: The final will be cumulative, but will mostly deal with integrals over curves, surfaces and three-dimensional regions. You will get three pages of formulas. The first two are the ones you have already seen at the second midterm. The third one is as follows:

Information for midterm The second midterm will be on Monday, May 19 in class. I will have an extra office hour Monday, 1-2. The material will go until the last homework assignment, i.e. until Section 7.5. You will get a sheet with formulas (see below). No other cheat sheet, books or calculators. Here are the formulas you will be given for your exam (you will not need to worry about the formulas for the flux).
You can find practice exams on the webpage listed below. Look at the samples for second midterms. You need not worry about problems concerning the flux. On the other hand, there may also be problems about path and line integrals in the first midterms listed there. Possible problems may be

Path and/or line integrals via parametrization, line integrals over gradient fields, how to detect gradient fields

Double and triple integrals, change of variable formula

parametrizations of curves and surfaces

areas of surfaces, integrals of functions over surfaces

The first midterm will be on Friday, April 18 in class. Unfortunately, I will be out of town on Friday, so no office hour on Friday. The material will go over the first three homework assignments, so basically chapters 1, 2 and 3.2. The problems will be similar to homework problems or to problems done in the lecture. You will be given a formula sheet, which will contain all the formulas on the following sheet which we have already used (you need not worry about formulas we have not covered yet, such as arc length, flow lines. divergence etc).
There are practice midterms and solutions at the following webpage. As the midterms there were given later in the course, there are also problems involving vector fields, curl etc. You need not worry about these problems. Just look at the first midterms.
