Announcements:

We'll be doing this course again for the Fall 2019 semester. Our first class will be Thursday, September 5.

Lectures will meet weekly from 8:00pm to 10:00pm in Emerson 210 (tentative) and online for distance students beginning Thurs, Sept 5. The recorded lectures should be available within 24 hours of the lecture.

TA Renee Chipman will conduct an optional online Q&A session (web conference) on Mondays, 2:00pm-3:00pm (this may changed). There will be time for additional questions from 3:00-3:30pm if needed. Recording will be available.

TA Jeremy Marcq will conduct an optional weekly Q&A session at 53 Church St. #203 on Mondays, 8:00-9:00pm (this may change). You may attend this in person or participate online. Recording will be available.

In addition, Robert Winters will hold an informal pre-class Q&A session at a location to be determined starting ~7:00pm. The purpose of this session is to resolve questions raised after you have struggled mightily with the homework but were either unsuccessful on some problems or have some doubts. Please don't use this session simply to get answers without having dedicated some time on every homework problem.


Regarding Homework: Your worked solutions should be submitted either in class or online via the Canvas site (primarily for distance students but available to all). We prefer that assignments be submitted on paper for those who attend class in person. Other students may submit their assignments as scanned PDF files. We will establish limits on file size, but a basic standard is that you should not scan at resolution greater than about 120dpi. Anything beyond that is not necessary for handwritten work and dramatically increases file size. Black & White scans are preferred unless there is a good reason to scan using color. Please also make sure that the contrast is adjusted properly so that all work is legible. Photographs of HW assignments will not be accepted - scans only. Based on class size and practical limits, we may select a subset of each assignment for grading. Solutions to all problems will be posted after the deadline.

Note: Starting with HW #2, there will be a zero tolerance policy for late HW (unless justified by personal or medical reasons). If you cannot submit HW in class you should scan and submit it no later than Saturday at midnight (Eastern time). You are advised not to wait until midnight just in case you have scanning troubles or other computer troubles. Staying current with the assigned HW is strongly advised.

Your lowest HW score will be dropped when determining course grades.

Teaching Assistant Renée Chipman will also be available for small group sessions and individual assistance on request (if agreeable times can be arranged).

Note: The "Graduate" credit option is primarily for students enrolled in certain Extension School graduate programs such as the "Math for Teaching" program. All other students (including high school students) should register for the "Undergraduate" option or the Noncredit option (if you will not be submitting homework or taking exams).


Calendar [Topics and homework assignments are posted here.]

Note: At a minimum, you should have successfully completed a full year of Calculus prior to taking Multivariable Calculus. Some topics from first-year Calculus (sequences and series, differential equations) are not essential for this Multivariable Calculus course, but you should be comfortable with all facets of differentiation and integration and their applications.

This course covers the following topics: Calculus of functions of several variables; vectors and vector-valued functions; parameterized curves and surfaces; vector fields; partial derivatives and gradients; optimization; method of Lagrange multipliers; integration over regions in R2 and R3; integration over curves and surfaces; Green's Theorem, Stokes's Theorem, Divergence Theorem.

Please take note that the pace of this course is quite fast and you will be required to do a substantial amount of homework. You should plan accordingly.


Textbook: Multivariable Calculus: Concepts and Contexts by James Stewart - either the 4th Edition (published 2010 by Brooks-Cole, ISBN: 0495560545) OR the 3rd Edition (published 2005 by Brooks-Cole, ISBN: 0534410049). The text should be available at The Coop or via the Internet. Note: If you can find an inexpensive copy of the 2nd Edition of the Stewart text or a comparable text, this should also work fine. Each homework assignment will be posted as a PDF for those with other editions of the text.

Mathematica (optional, but worth investigating)
If you would like to experiment with Mathematica to graph parameterized curves and functions f(x, y), find level curves, and much more, here are a few labs that will introduce you to this software and show you how to do most of the basic things that are relevant to Math E-21a. You can also cut and paste images produced by Mathematica into other documents and print some pretty dazzling graphics.
