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 Yang).

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 1: Workbook and Lecture Notes. Strongly Recommended.
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 Will Not Work: You will want the current edition of this---everything has been completely reworked and an old edition won't work.
Buy Workbook at the Wash U Bookstore: It looks like the link above will sell you a copy, but I have been told that all the print copies have been sent to the Wash U Bookstore, so buy it there!

Text 2: Calculus Textbooks. NOT Recommended for most students:
In the past I have recommended traditional textbooks. I still like these books, but I have found that most students do not find these useful and more of a waste of money. That said, here are two recommendations:

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.
Learning Center: PLTL Page

Residental Peer Mentors (RPMs)
Residential Peer Mentors (RPMs) offer drop-in help hours on the South 40 to provide support for Calculus students. Unlike PLTL, RPM hours are unstructured, so you can use them for just about anything: if you have a quick question about WebWork, if you want to review concepts or work on problems with classmates, or if you are just looking for a regular time and place to work on Calc. RPMs also can help with study strategies and provide advice on how to succeed both in Calc and at WashU. Schedules and links are posted at the Learning Center's mentoring calendar. The RPMs will also post announcements weekly with any updates or cancellations.
While sessions are typically held in residential colleges on the South 40, there will also be some sessions held remotely via Zoom this semester. There are currently four Calc III RPMs who will hold sessions spread throughout the week, and you are welcome to attend ANY RPM's hours, not just the ones held in your residential college!

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 Thursday 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!
Webwork Due Date Logistics: Whatever is covered by Wednesday of lecture of "fair game" for webwork due on Thursday. We may postpone sets that appear due that week based on what happens in lecture that week.

Exam Schedule
Exam Schedule
Exam 1 Tues Sept 20, 6:30-8:30PM
Exam 2 Tues Oct 18, 6:30-8:30PM
Exam 3 Tues Nov 15, 6:30-8:30PM
Final Thurs Dec 15, 3:30-5:30PM

Final Exam
The final exam will be as scheduled.

Study Suggestions - What to do daily and weekly

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.

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 [90,93). This means that anything in this interval is an A- (i.e., no rounding).

A [93,infinity)
A- [90,93)
B+ [85,90)
B [80,85)
B- [75,80)
C+ [72,75)
C [68,72)
C- [65,68)
D [55,65)
F [0,55)

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

Class Recordings:
We will be doing our best to record, through zoom, exactly 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.
I am certain that the value you get from attending class will be much greater than watching any videos.

Other Wash U Policies and Resources:
Covid, Sexual Assault/Harassment, Disability Resources, Military Service, Preferred Name and Pronouns, Emergencies, Academic Integrity, Student Resources, Religious Holidays and more can be found at:

Tentative Schedue:
The schedule is tentative and will be updated regularly.
We will do our best to follow this schedule but don't be surprised if topics are shifted from one week to another as the semester progresses.
