Math 31CH - Honors Vector Calculus, Spring 2021

Main lecture A00: TuTh 2:00pm–3:20pm, zoom link is accessed through canvas. The lectures are recorded on the zoom cloud so that you can watch them later (zoom cloud keeps them 30 days, they should be in "Media Gallery" on canvas for the whole quarter).


We'll use canvas Canvas( for a lot of the day to day announcements, and for keeping track of the grades, etc.


We will be using Piazza for class discussion. The system is highly catered to getting you help fast and efficiently from classmates, the TA, and myself. Rather than emailing questions to the teaching staff, I encourage you to post your questions on Piazza. If you have any problems or feedback for the developers, email

Homework will be announced on canvas and submitted through gradescope.


John Hamal Hubbard, Barbara Burke Hubbard, Vector Calculus, Linear Algebra, and Differential Forms: A Unified Approach, fifth edition.

Older editions may also be usable to some degree, but the numbering is off, and we will be posting exercises from the fifth edition.


The plan is to cover sections 4.1, 4.5, 4.8, 4.9, 4.10, 5.1, 5.3, 6.1–6.11 (the plan is to try to get to at least 6.10).

Current plan is to have the two exams run on the Thursdays/Fridays (see below) in weeks 4 and 8.


Exams and homework will be done through gradescope. Access will be through canvas.

Office hours: Right after lecture, TuTh 3:20pm–4:20pm, same zoom link as lecture, I may stay longer if there are questions and I don't have another appointment. On the other hand, if everybody leaves, then zoom kicks me out after 40 minutes of being by myself, so it isn't totally assured that I'll be around after 4pm if nobody was there at the beginning.


A01: Finley McGlade,, office hours: see canvas.


Grades will be based on the percentages below. Curve will be applied if needed. The grading scale without a curve is the standard 90-80-70-60 (or more precisely with the +'s and -'s: 97-94-90-87-84-80-77-74-70-60), those grades you are guaranteed (i.e., 90 and above guarantees an A), but the curve may improve your grade.

Exam 1: Thursday/Friday, Apr 22nd, online/gradescope.

Exam 2: Thursday/Friday, May 20th, online/gradescope. (On material since exam 1)

Final Exam: June 8th, online/gradescope. (Comprehensive)

Homework: Weekly, due thursdays (except on exam week), collected at gradescope

How the grade is computed:

40% (Exam 1 and Exam 2 each 20%) + 40% (Final exam score) + 20% (Homework score)

Exam Policies: Open book (the course textbook and your notes), but no internet use, no calculators, no software, and you must work on the exam on your own without help of others. Academic integrity is taken very seriously, especially in these online times.

Midterm exams will be open for a window starting in the evening of the Thursday, and going to the evening of the Friday.
