This is a website built for math323-05-f19 and math323-06-f19. If you have an idea to improve this space, please email eppolito-at-math-dot-binghamton-dot-edu with your suggestion; I would like this space to be as useful to students as possible…

The official course page is at the following link:

https://www2.math.binghamton.edu/p/calculus/math_323/start.

Its contents are our syllabus.

Your instructor is Chris Eppolito (hey, that's me!). Email me at eppolito-at-math-dot-binghamton-dot-edu for anything regarding this class. Be sure to include your name and section number in the email.

Section 5: MWF 14:50 - 16:20 in LH 3

Section 6: MWF 16:40 - 18:10 in CW 323

Our help room for this class is WH 233. Please see the schedule for my hours. I can also meet by appointment (email me to set up an appointment).

You can visit any Calculus III instructor in the help room, and I encourage you to do so! Different folks think differently; maybe someone else thinks more like you, and you can get help from them too.

*Multivariable Calculus (8e)* by Stewart

The textbook (as an e-book) comes with a subscription to WebAssign, so just get that…

See the official grading distribution.

Reasoning in three dimensions. Calculus of functions in several variables. We will cover most of chapters 12 - 16 in the textbook, together with some small excursions as I see fit.

This class uses WebAssign for online homework assignments. You are expected to check WebAssign daily, and to know when assignments are due. *I will NOT notify you of assignment due dates* (all due dates are already posted).

Email me if you need the key to our class in WebAssign.

I sometimes assign written homework to collect in class.

Here are some practice problems (updated 16 November 2019) I like. Check back for updates…

Quizzes will be given frequently throughout the course. Quizzes are intended to check that you understand basic concepts from previous classes and from assigned reading.

I typically grade quiz questions on a 5-point scale. The following is a ROUGH guide to interpreting each score.

**5**: Understands concept, with minor errors**4**: Mostly understands concept, with errors in execution or minor misunderstanding**3**: Conceptual misunderstanding present, but not yet serious**2**: Major conceptual misunderstandings, with shallow understanding (if any)**1**: Mostly nonsense, with serious errors**0**: Demonstrates no understanding of the topic

Here are some useful technological tools for this class, together with some descriptions.

- Mathpix is a browser 3D graphing calculator. The interface is self explanatory, produces very nice pictures, and doesn't use a lot of computing power.
- GeoGebra is a math learning software (that link is to the browser 3D graphing calculator). You can download a copy (for Linux, Mac, or Windows) and write your own sheets, too! There is a learning curve…
- Academo is a browser 3D graphing calculator. It provides nice shading, but has a limited rotation.
