*Div, Grad, Curl, and All That: An Informal Text on Vector Calculus*,
by H. M. Schey, ISBN 0393925161.

A quick summary of basic concepts of vector calculus for a quick review.

A set of notes on the Hessian that we covered in class.

A set of notes on differential forms that we will cover in class.

Finally, for practice on background in Calc III, see for example the online Paul's notes on Calc III.

A few sample extra questions to try before the final.

The grading scheme is given below:

$\begin{multline} \text{Grade} = 0.2 \times \text{(Homework)} + 0.2 \times \text{(Exam 1)} \\ + 0.2 \times \text{(Exam 2)} + 0.4 \times \text{(Final Exam)} \end{multline}$

To account for bad exam day, etc..., an alternative grade will be computed as follows

$\begin{multline} \text{Grade} = 0.2 \times \text{(Homework)} + 0.1 \times \text{(Exam 1)} \\ + 0.1 \times \text{(Exam 2)} + 0.58 \times \text{(Final Exam)} \end{multline}$

A second alternative (to account for bad final day) will be follows

$\begin{multline} \text{Grade} = 0.2 \times \text{(Homework)} + 0.3 \times \text{(Exam 1)} \\ + 0.3 \times \text{(Exam 2)} + 0.18 \times \text{(Final Exam)} \end{multline}$

The highest of the three will be used for your grade. Notice that in the alterative schemes, the score does not sum to 100 percent. That is on purpose! You should count on the first scheme, the second/third schemes are only to account for things going terribly terribly wrong on one of your exams.

**Exam 1: Monday, Feb. 27, (in class)**

**Exam 2: Wednesday, Apr. 5, (in class)**

**Final Exam: Friday, May 12, 10:00-11:50am (same room as the class),** Comprehensive, think of the final exam as half exam 3 and half comprehensive final

**Exam Policies:**
No books, calculators or computers allowed on the exams or the final.
**One page (one sided) of notes allowed on the exams.**

Assigned weekly (some weeks may be skipped). Homework will be done
using WeBWorK. See:

https://lebl-titanus.ms-2345.okstate.edu/webwork2/MATH4013/

You have been sent instruction on how to log in by email.

Some homework may be paper based. I will announce in class and update this page if that happens.

Lowest 2 homework grades dropped (so **no late homeworks**).

**No makeup or late homework** (two lowest are dropped anyhow), but feel free to turn homework in **early**
if you you cannot for whatever reason turn it in on time.
For exams, there will be
reasonable accommodation 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 at least two weeks befre the final exam week, so
so that we can figure out what to do.

See the official syllabus attachment, for some more information.

Wolfram Alpha (http://www.wolframalpha.com). 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 do manage to find them, you
will not learn anything and you will see the result of this on the exams.
Also it is *considered cheating (and plagiarism)* to find solutions online
and claim them as yours. Don't do it!

It never hurts to learn how to use LaTeX if you want to type up stuff with lots of math. It not only increases legibility of your work, it also increases your nerd factor by an order of magnitude (that's a good thing). For easy to use LaTeX frontends try TeXworks (Linux, Windows, Mac) or TeXShop (Mac). Or perhaps give LyX (Linux, Windows, Mac) a go. Lyx might be the easiest of the bunch, though it is not as flexible.

The easiest way to type LaTeX without installing anything is online on Overleaf.
