Math 2163 - Calculus III - section 61993

Lecture: MWF 9:30AM - 10:20AM, Classroom Building 321


The main text we will follow (and which you probably already have) is:

Jon Rogawski, Colin Adams, Calculus: Early Transcendentals, Third Edition, 2015, W. H. Freeman and Company.
Other editions are fine, chapter/section numbers might be different, but you need to have a webassign access code.
Don't get the kindle version, it just doesn't work.
We will be covering things from chapters 11-17 (mostly 12-16)

It's always useful to have some other sources. The following are free online:

Gregory Hartman, APEX Calculus ( (PDF).
The corresponding material is chapters 9-14, which is the 3rd volume of version 4.0 (you can get a printed copy for $15).

Lars Jensen, Active Calculus - Multivariable ( (webpages).
Many interactive practice exercises. The downside is that it doesn't cover everything we will do.

Paul Dawkins, Paul's Online Notes - Calculus III ( (webpages).

What's the Course About:

We will learn multivariable calculus by generalizing the single-variable notions to functions of more than one variable. We will study in particular analytic geometry in three dimensions and basic notions of vectors, and the beginnings of vector calculus.

Prerequisites: Calculus I and II with grade C or better.


Grade distribution is as follows:

50% - 3 exams, the lowest grade is dropped, so the 2 best scores are counted.

30% - Final exam.

10% - Quizzes.

10% - Webassign.

As usual, 90% and above guarantees an A, 80% and above a B, 70% a C, and 60% and above a D. Curve will be applied if needed, and so those cutoff percentages could move downwards, but only if it is deemed necessary.

Exams, Quizzes:

Exam 1: Friday, September 20th, (in class)

Exam 2: Wednesday, October 23rd, (in class)

Exam 3: Friday, November 22nd, (in class)

Final exam: (as per university schedule) Friday, December 13th, 8:00-9:50am, same room as class

Quizzes will be in-class. They will be short 10-15 minutes. I will try to do at least one weekly (on monday). 2 lowest quiz scores will be dropped.

No calculators are allowed on the quizzes or exams. Trust me, you will not need them, and from experience in this sort of class, they just slow you down. Feel free to use them when studying and working on homework.

Missed Work:

No makeup quizzes (we are dropping the lowest 2 anyhow). There will be reasonable accommodation for more substantial missed work if you have a valid and documented reason, and the documentation is provided in advance unless absolutely impossible. If you have a university approved (see the syllabus attachment) final conflict exam, you must tell me no later than two weeks before the final, so that we can figure out what to do.


Mandatory, but not taken. Students who do not attend class regularly often do much worse.


WebAssign will be used in this class for homework:
Class key: okstate 3623 9685


We will be using Gradescope ( for all exams and quizzes. I'll add you to the class after the first week or so, and you'll get an email on how to log in.

Syllabus attachment:

See the official syllabus attachment, for some more information.

Interesting links:

Wolfram Alpha ( It's like Google for math.

Speaking of Google: try typing something like x^2-y^2.

Although no, Google will not likely solve your homework problems for you. Even if it did, it would not be a good idea. The reason for doing the homework is to learn how to do it. If you simply try to find solutions online, and did manage to find them, you will not learn anything and you will see the result of this on the exams.

If you want to type math, I recommend learning LaTeX. Best way to do that is to use Overleaf online.
