The course grade will be calculated as follows, out of 660 points total:
You can check your grades via Moodle.
Your grade total will be converted to a letter grade according to the following scale:
|A+||≥ 630||B+||≥ 520||C+||≥ 450||D+||≥ 380|
|A||≥ 570||B||≥ 490||C||≥ 420||D||≥ 350|
|A-||≥ 540||B-||≥ 470||C-||≥ 400||D-||≥ 330|
It is possible to take the course for 4 credits rather than 3, at the cost of extra homework questions and more difficult exams. If you want to do this, you need to register at the math office in Altgeld Hall soon after the start of the course.
There will be 10 homework assignments, to be turned in at the beginning of class the day they are due. Of these homework assignments, the top 8 homework scores will determine your grade. Each assignment is graded out of 20 points, for a total of 160.
If you cannot attend class, you should submit a scanned copy or a photo of your homework as a single PDF file by e-mail before class begins. Please avoid doing this unless it's necessary, since it is more work for the grader.
If the homework assignment is received after class on the due date, but before the next class, it will be accepted as late, for a 2-point penalty. Homework will not be accepted after the next class for any reason.
There will be three evening midterm exams: Wednesday 9/18, Wednesday 10/16, and Wednesday 11/20 from 7pm to 8:30pm in Noyes 161. Correspondingly, three lectures will be canceled, not necessarily in the same week as the midterm exams. These are marked in the syllabus below.
The final exam will not be combined; the date and time for each section is listed at the end of the syllabus. By default, you should take the final exam for your section; if you have a good reason why you need to do something other than that, talk to me in advance.
This course is based on several textbooks with a lot of overlap; read whichever ones help, or read my lecture notes (or both). In the syllabus, I will refer you to sections of the textbooks below that cover the relevant material.
The syllabus below will initially describe a tentative plan for what topics will be covered when. As the semester progresses, I will update the syllabus with lecture notes, adjustments to my plans for the future, and links to homework assignments.
Note: originally this page contained lecture notes for each day of class. I've taken these down because the next semester's notes fix some typos and minor errors and are generally better in every way. So if you are looking for my lecture notes, please go to the page for the Spring 2020 semester instead.
