Math 2163 - Calculus III - section 61332

Lecture: MWF 12:30pm–1:20pm, Agricultural Hall 201



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

Jon Rogawski, Colin Adams, Robert Franzosa, Calculus: Early Transcendentals, Fourth Edition, 2019, W. H. Freeman and Company.
Other editions are fine, chapter/section numbers might be different, but you need to have the Achieve access code.
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. In particular, we will study analytic geometry in three dimensions, 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% — Achieve.

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: Wednesday, September 21, (in class)

Exam 2: Wednesday, October 26, (in class)

Exam 3: Wednesday, November 30, (in class)

Final exam: (as per university schedule) Wednesday, December 14th, 10:00am–11:50am, same room as class.

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

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, the "answer" that is being graded is actually your work, so points may/will be taken off for incomplete or illegible work. This includes missing or incomplete notation, don't take shortcuts! E.g., don't forget all those \(=\) signs, don't forget the \(dx\)s etc.

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.

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 below) 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.



Homework will be done on Achieve:
Your book came with access to Achieve.
The invite link to the course is on canvas (as an announcement).



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


Free tutoring

The Mathematics Learning Success Center (MLSC) offers a free drop-in tutoring, no appointments necessary, at our physical location on the 5th floor of Edmon Low Library. Our hours are: Sunday 1:00 PM to 9:00 PM, Monday–Thursday 9:00 AM to 9:00 PM, and Friday 9:00 AM to 5:00 PM. MLSC tutors are trained to help you become an independent learner, so please bring your course materials and come ready to engage with the mathematics. You may also chat online with an MLSC tutor on our Discord Server during our hours of operation. After hours, students can post questions in the chat channels and tutors will respond when the MLSC reopens. Information for how to log on to the MLSC Discord server and information about other services are located on our website.


Masks/COVID etc.

OSU encourages faculty, staff and students to wear a mask indoors in public settings during periods of high community transmission regardless of whether you are fully vaccinated, consistent with the current CDC recommendations. This is especially important in classrooms and laboratories because people are together for long periods of time. Wearing a mask during class not only protects you but also helps protect those around you who may be more vulnerable. This is a simple way we can look out for all members of the Cowboy family. If you feel sick, do not attend class. Contact University Health Services at 405-744-7665 immediately, and communicate with me as soon as possible about any work you miss.


Syllabus Attachment:

See the official syllabus attachment, for some more information, like deadlines and some university-wide policies.


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.
