Lecture is MWF every week. You must attend this.

Communication: We will make announcements in canvas announcements. If you have questions about the material, please visit office hours or post in Piazza (linked in canvas). If you have administrative questions, please email and copy in all instructors (Prof Thornton, Prof Cao and Prof Rodsphon).

Help and Assistant Office Hours: Mathematics Help Room.
You are encouraged to attend at any open time--all available assistants should be able to help you with our course.

Text 0 (Lecture Notes): Calculus 3 Lecture Workbook
You will almost certainly want a physical copy of this to work through as it contains the problems that we will work through in lecture. Solutions/answers will be posted in the schedule above as we work through the book.
Feedback from students: Most, but not all previous students generally reported this text as being useful. Many students reported that every student should be required to have a physical copy of this workbook.
Old Editions: You may be able to get an older edition of the workbook. This might work for you, but it will have issues--there were some updates to the workbook this year.

Text 1 (Textbook): Stewart, Calculus, Early Transcendentals, 9th edition.
We will plan to cover most of chapters 12-16
Officially, I will be using the 9th edition, Early Transcendentals, but only as a rough guide. You will okay with any edition (5-9) of this textbook.
Feedback from students: In past semester, many students have reported that they bought this book but did not use it. Despite these students' reports, we still believe that it is a useful reference. I recommend going the cheapest route possible, some options are listed below. I see absolutely no advantage to the 9th edition over the 8th or 7th editions. The best students both read the book as well as do the exercises in the book.

There are many options for acquiring this book, and I'm sure you can find additional options.
Note, for some reason some of the amazon links below look like they link to the "International Metric Version." I've never seen this book before, but it is probably exactly the same except for meters instead of feet. I'm quite certain that you will be fine purchashing this version.
For my money, I would buy a copy of the 6th or 7th edition, used, from Amazon for about $10-20.
Webassign is NOT necessary. If you order the Stewart ebook through the publisher, you might be given webassign access, but this isn't important for our course.

Textbooks, Digital vs Physical:
While I've seen more and more students effectively use digital textbooks, I believe that most, if not all, students learn more easily from a physical textbook. The work in the course is designed for you to actually physically write and solve problems on paper. I strongly suggest you get a physical workbook. A physical Stewart text is actually cheaper than a legal digital version.

Textbooks: WebAssign: Not Required!
The digital version of the Stewart text is generally delivered using WebAssign. You do not need this! See the textbook information above. If you buy the digital Stewart text, then you will probably buy this, but it is not necessary!

Are you in the right class? We want you to succeed, without repeating a large amount of material.
Math 131 Calculus 1: Limits, Derivatives, maxima and minima, L'Hopital's Rule
Math 132 Calculus 2: Integration, area, volumes, surface area, infinite series, Taylor series
Math 233 Calculus 3: Three space, partial derivatives, multiple integration, Green's theorem and vector calculus

Google Course Calendar:
You can find a calendar on the course including instructor office hours below.

Discussion Sections
You will meet with your Assistant to Instructor (AI) every Tuesday (starting with the first Tuesday of classes). In these meetings, you will learn new material and topics as well as work on problem solving. Come to these meetings prepared by doing your homework. You will have group work to do that will be graded and part of your grade.

Where to go for Help:

Peer Led Team Learning (PLTL)
The PLTL program is voluntary but highly recommended. If you want to participate, you must sign up the first week of class by completing an application: PLTL Applications
Applications are available on Aug 30 and will be closed on Friday Sept 3.
Learning Center: PLTL Page

While you are free to use any calculator for your homework, you will not be allowed to use a calculator for exams:

You can find your grades, access WeBWorK and more at Canvas. All the sections are merged into section 1, so log on to Math 233, section 1.

Webwork is due every Wednesday evening.
To log in, go to Canvas and click on "Assignments."
You will do weekly homework online. You are responsible for making sure this is done by the due date.
Important! There may be more than one set due each week!
Collaboration: Feel free to work together but remember, you have to be able to perform by yourself on exams!

Recommended Homework
The textbook contains an enormous number of homework exercises at the end of each section. You will get the most out of the course if you do all of these. I will recommend a subset of these problems for you to focus on. These will not be collected or graded.

Study Suggestions - What to do daily and weekly

What to do every week?
  1. Read the Stewart text for the relevant sections to be covered.
    (Hint: Most students don't do this. If you do this you will be ahead of the curve.)
  2. Tuesday: Attend your discussion section.
  3. Do the additional workbook problems that weren't in the lecture. (You can find answers in "Canvas-->Files".)
  4. Attend help sessions, office hours and the Mathematics Help Room if (when) you get stuck on the workbook problems, webwork problems or you just don't understand. Drop by any of those locations and just hang out--maybe someone will ask a question you have.
  5. Attend PLTL on the weekend if you have signed up for PLTL.
  6. Attend RPM hours for help.
  7. Do the Webwork homework.
  8. Look at the Google Course Calendar.

Grades: Your final grades will be computed according to the following formula and grading scale.
		Grade = 0.75*( E1 + E2 + E3 + 2*E4 - min(E1, E2, E3, E4))/4 + 0.15*(WeBWork) + 0.10*(GroupWork)
Basically this means that all exams are weighted equally and worth 75% of your grade. The final exam can replace your lowest semester exam. Webwork is worth 15% of your final grade, discussion sections are worth 10%.

We will drop the lowest three discussion section grades, the lowest five webworks. (We increased the number of webwork drops to 5 because you do not have to do Green's Theorem webwork, but you can do that assignment in order to drop a different webwork that is low.)

A note on webwork grades: There may be multiple webwork assignments due every week. In computing your grade, we will scale these so they are all equally weighted and use these scaled scores for computations.

A note on rounding: For example, the A- interval is [85,90). This means that anything in this interval is an A- (i.e., no rounding).

A [90,infinity)
A- [85,90)
B+ [80,85)
B [75,80)
B- [70,75)
C+ [65,70)
C [60,65)
C- [55,60)
D [50,55)
F [0,50)

Pass/Fail Policy: You must get at least a C- to earn a "Pass".

Disability Resources (DR):
Special accommodations for exams are offered to students who have registered in a timely manner at Disability Resources (DR). Information about DR may be found at https://students.wustl.edu/disability-resources/.

For our class, this means that you must let your instructor know of your accommodation and we will work with you.

Covid Policies:
Students are expected to follow university-mandated COVID safety procedures.
If you are sick, quarantined, or do not pass WashU self-screening, do not come to class in person. Watch the recorded lecture for that day instead.
If you miss a discussion section that will count as one of your dropped discussion section (that is what hey are for). If you miss an exam, let us know.

Class Recordings:
We will be doing our best to record, through zoom, one lecture every day of lecture. Students will not be admitted into class via zoom but can view the recording after the lecture when we post it in canvas.
There are also videos from 2020 that you might find helpful. You can find these in Canvas
I am 150% certain that the value you get from attending class will be much greater than watching any videos.
