Math 2163 - Calculus III - section 21808

Lecture: MWF 1:30pm–2:20pm, Human Sciences 326 Lectures are recorded and posted on youtube (playlist). Links are on canvas.


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 12–17

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:

10% — Each of 3 in class exams.

30% — Final exam

20% — Your best exam score (either one of the midterm exams or the final)

10% — Quizzes.

10% — Webassign.

20% — Two in class exams

20% — Final exam

10% — Your best in-class exam score (either one of the two midterm exams)

15% — Quizzes.

15% — 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 at the end if needed, and so those cutoff percentages could move downwards, but only if it is deemed necessary.

Exams, Quizzes:

Exam 1: Monday, February 10th, (in class)

Exam 2: Wednesday, March 11th, (in class)

Exam 3: Wednesday, April 22nd, (in class)

Final exam: (as per university schedule) Wednesday, May 6th, 2:00pm–3:50pm, same room as class Will be available on Wednesday, May 6th at 6am through gradescope. Will be up for 24 hours after that and you will have 3 hours to finish it once you start. It will be the same idea as the quizzes except it will be longer and have a longer time limit.

Quizzes will be in-class. They will be short 10 or so minutes. I will try to do one weekly, on Wednesday, end of class. Lowest 2 quiz scores will be dropped.

After the move online, quizzes are submitted through gradescope. On midnight from Tuesday to Wednesday, the quiz will be available at gradescope, you will work out answers on a piece of paper, take a picture, and then submit through gradescope. Note that the time is limited once you start.

Quizzes will be out of 25 points. Two questions, 10 points each, plus 5 points for turning the quiz in (even if it is empty).

On most questions (quizes/exams), 10% of the points will be for writing complete legible work (for example all those \(dx\)s and all those \(=\) signs), unless the problem says otherwise. It may be possible to get this 10% (or some of it) even if there are some mathematical errors.

Nongraphing calculators are allowed on the quizzes or exams. But trust me, you will not need them, and from experience in this sort of class, they just slow you down.

One sheet (letter size) of hand-written notes will be allowed on exams. Feel free to use both sides. This is only for exams. Notes are not allowed on quizzes. Online quizzes and exams are open-book, open-notes, however, you are not allowed to talk about the exam/quiz to your classmates, nor anyone else, you are only allowed to work on the exam/quiz on your own. You are not allowed to use the internet nor any online resources during the exam/quiz except for the online version of the book if you use that. You are allowed to use any of the books listed on this syllabus: our main text Rogawski, but also APEX Calculus, Paul's Online Notes - Calculus III.

Exams/quizzes will be graded/returned through gradescope, see below.

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 8653 3509


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. This is where you will be able to view your graded exams/quizzes when I am done grading.


Roughly we will cover the following sections:

Chapter 12: 12.1, 12.2, 12.3, 12.4, 12.5, (part of 12.6), 12.7

Chapter 13: 13.1, 13.2, 13.3, 13.5

Chapter 14: 14.1, 14.2, 14.3, 14.4, 14.5, 14.6, 14.7

Chapter 15: 15.1, 15.2, 15.3, 15.4, 15.5, 15.6

Chapter 16: 16.1, 16.2, 16.3

Chapter 17: 17.1

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.
