Office: SciCtr 434
Math21a: Multivariable Calculus This course extends single variable calculus to higher dimensions. It provides vocabulary for understanding fundamental equations of nature like weather, planetary motion, waves, heat, finance, epidemiology, or quantum mechanics. It also teaches important background needed for statistics, computer science, bioinformatics, etc. You learn tools to describe curves, surfaces, solids and other geometrical objects in three dimensions and develops methods for solving optimization problems with and without constraints. The course prepares you for advanced study in other fields of mathematics and its applications. Furthermore it sharpens your abstract thinking and problem solving as well as visualization and computing skills. Math21a together with Math21b gives a solid background in multivariable calculus, linear algebra and differential equations.
Lectures: These course offers lectures at MWF 9 AM, MWF 10 AM, MWF 11 AM, TTh 10-11:30 AM, TTH 11:30-1 PM. This course is taught in sections rather than in a large lecture. This allows you to get involved more and to ask questions during lecture.
Prerequisites: Single variable calculus like Math 1b or equivalent
Course change fees: All course change fees are waved for students who change between Math 21a, Math 23a, Math 25a and Math 55a until the 5'th Monday of the term.
How to Sign Up: Input your time preferences starting Monday, August 31, and no later than 12:00 pm (noon) on Thursday, September 3rd. See the sectioning and advising page from th e Mathematics department.
Introductory Meeting: Tuesday, Sept 3, 2009, Sci Center C, 8:30 AM.
Lectures start: Wed Sep 9 for MWF sections Thu Sep 10 for TTh sections

Text Multivariable Calculus: Concepts and Contexts, 4" by James Stewart: we use the fourth edition. This book is used by all sections. The newest Stewart Multivariable Calculus Edition 4E as the ISBN-13:978-0-495-56054-8. It is contained also in the "fat version" ISBN-10: 0-495-55742-0 which contains all single variable. A copy also in the Cabot library on reserve.
Math Question Center MQC The Math question center (MQC) is open Sundays - Thursdays 8:30 - 10:30 pm (with occasional breaks for holidays). Place: Sunday nights, in SC 112; on Monday-Thursday nights, in SC 222.
Homework: Homework is assigned each lecture and due the next lecture. In this course, no late homework is accepted but a fraction of the HW score with weight of a week can be discarded and used as "jokers", for example, in case of sickness. You are encouraged to discuss solution strategies with classmates, your section leader or your CA but you must write up answers yourself in your own words. As with any academic work, external sources which were consulted should be cited. For example, if you use Mathematica for a computation, acknowledge it and add the output.
Computers: The course features a Mathematica project, which introduces you to an advanced and industrial strength computer algebra system. Mathematica 6. At the end of the semester you submit a short project. The actual lab will be posted here later in the semester. The work load for the lab is not too large, a couple of hours.
Exams: First Hourly: Tuesday, Oct 6. 2009, Hall C, 7-8:30 PM
Second Hourly: Tuesday, Nov 3, 2009, Hall C, 7-8:30 PM
Final Examination: TBA Computers and other electronic aids are not permitted during exams.
