Lecture:

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 Roberts, Prof Chi).

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. You will do your work and take notes in this book. Solutions/answers will be posted in canvas as we work through the book.
Feedback from students: Most previous students generally reported this text as being useful to their learning. Many students have 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, Orange Cover, Edition 5. Everything has been completely reworked and an old edition won't really work.
Buy Workbook at the Wash U Bookstore: There is a weblink to buy the book, but all the copies should be sent to the Wash U Bookstore, so just 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:

• Stewart, Calculus, Edition 7 (any edition is fine) This is a nice textbook, and a used copy is easy to find. It is especially good for examples and exercises.
• Lang, Calculus of Several Variables This is a nice mathematics book. The writing is great. The theory is great, but it is a bit light on exercises and practical problems. It is also a bit more expensive, but I like the book.

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

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 will count toward your grade.

Where to go for Help:

• Instructor Office Hours.
• Assistant to Instructor Office Hours: Mathematics Help Room. Available M-F between 10AM-4PM.
• The Learning Center
• Engineering Tutoring Services (only available to EN students)
• CTL Mentoring
• CTL RPM Schedule

Peer Led Team Learning (PLTL)

The PLTL program is voluntary but highly recommended. If you want to participate, you must sign up during 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!

Calculators:

While you are free to use any calculator for your homework, you will not be allowed to use a calculator for exams:
NO CALCULATOR ALLOWED AT EXAMS

Canvas

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

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's lecture is "fair game" for Webwork due on Thursday of the same week. We may postpone sets that appear due that week based on what happens in lecture that week.

Exams:

• Exams will be a mix of multiple choice questions (probably around 15-20 of these) and hand graded questions (probably 2 of these).
• The final exam will be entirely multiple choice.
• You will not be allowed anything other than writing tools at the exams.
• Find your room and seat before the exam: Exam Seating
• View past exams here: Old Exams (some semesters are more helpful than others).
  
• Find all your grades here: Canvas. Webwork grades will be uploaded to Canvas at the end of the semester.
• Do not miss an exam. Make up exams (on different days) are not given. If something happens (you are sick, family emergency, etc) contact Prof. Blake Thornton as soon as possible. You may be able to receive an excused absence for one exam. (In the case of an excued exam, there is no make-up exam, but we do excuse exams so that your exam average will be a weighted average of your other exams---talk to your instructor for details.)
• The final exam covers all material from the course.
• The Exam schedule can be found on this page, in the course description in Webstac.
• Curving:
  • If the average of the exam is below 70% then all exam scores will be adjusted upwards by adding a constant to everyone's score so that the average is 70%.
  • If the average of an exam is above 70%, no adjustments will be made.
  • Example: You get a 80% on Exam 1 and the actual average of Exam 1 is 50.0%. Thus, everyone will receive 20.0 "curve points" for Exam 1. Your score (to be used in grade calculations) for Exam 1 will therefore be 100%.
    Do not expect anything like this to actually happen---exams will be written with an expected average of close to 70-75.

Study Suggestions - What to do daily and weekly

• Read/skim the upcoming section in the workbook before class.
• Do all the problems in the workbook! You can find answers in "Canvas-->Files". (It is okay to skip those marked "overkill" or "difficult".)
• Do the WebWork homework early.
• Go to your discussion section prepared. This means that you have worked on the relevant workbook problems and started the WeBWorK problems.
• Go to PLTL (if you are signed up) or do the PLTL problems (they are typically available after the PLTL groups get them).
• If you don't understand something, visit your instructor and Assistant office hours. You can see Mathematics Help room for assistant office hours and other suggestions on where to get help.
• Attend office hours and the Mathematics Help Room. Drop by any of those locations and just hang out--maybe someone will ask a question you have.
• Attend RPM hours for help.

Extra Credit:

Class extra credit will be awarded by participation in course evaluations. Participation rate will be checked on Thursday, Dec 14, at 3:00PM and points will be awarded to entire class course grade according to table. This is often enough to bump several people from one grade level to another.

Participation Percent	Extra Credit
[0,80)	0.00%
[80,85)	0.50%
[85,90)	0.55%
[90,100]	0.60%

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) + (Extra Credit)
		      

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%.

In computing discussion grades, we will drop the lowest three discussion section grades. These dropped grades are for you being sick, at athletic events, etc. If you are sick more than three times, come see an instructor. For webwork average, we will drop your 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). But, see the Extra Credit above which can help bump you over to the next grade.

A+	TBA
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".
