Math 241, Calculus III, Honors section
The focus of this course is vector calculus, which concerns functions
of several variables and functions whose values are vectors rather
than just numbers. In this broader context, we will revisit notions
like continuity, derivatives, and integrals, as well as their
applications (like finding minimal and maxima). We'll explore new
geometric objects such as vector fields, curves, and surfaces in
3-space and study how these relate to differentiation and
integration. The highlight of the course will be theorems of Green,
Stokes, and Gauss, which relate seemingly disparate types of integrals
in surprising ways.
Your course grade will be based on:
- Weekly Homework (15%). Homework will be
assigned during each lecture and due at the beginning of class
each Tuesday. No late homework will be accepted; however, your lowest
homework grade will be dropped so you are effectively allowed one
infinitely late assignment. Collaboration on homework is permitted,
nay encouraged. However, you must write up your solutions individually
and understand them completely. You may use a computer or calculator
on the HW for experimentation and to check your answers, but may not
refer to it directly in the solution, e.g. "by Mathematica" is not an
acceptable justification for deriving one equation from
another. (Also, computers and calculators will not be allowed on the
exams, so it's best not to get too dependent on them.)
- Three in class exams (20% each). These will be closed-book,
calculator-free exams, though you will be allowed to bring one piece
of paper with handwritten formulas. They will be on Thursdays, in
particular on February 14, March 6, and April 10.
- A final exam (25%) Our exam is scheduled for Monday, May 5
The required text for this course is:
- M. Lovric, Vector Calculus, Wiley, 2007
A change of perspective is sometimes helpful to clear up confusion.
Here are two other vector calculus sources you might find helpful.
- H. M. Schey, Div, Grad, Curl, and All That, W. W. Norton. A classic informal account of vector calculus from a physics point of view.

streetwise guide, Freeman.
