- Math21a: Multivariable Calculus.
- extends single variable calculus to higher dimensions;
- provides vocabulary for understanding fundamental
equations of nature like weather, planetary motion,
waves, heat, finance, epidemiology, or quantum mechanics.
- teaches important background needed for statistics,
computer graphics, bioinformatics, etc;
- provides tools for describing curves, surfaces, solids
and other geometrical objects in three dimensions;
- develops methods for solving optimization problems with
and without constraints;
- prepares you for further study in other fields of
mathematics and its applications;
- improves thinking skills, problem solving skills,
visualization skills as well as computing skills;
-
- Prerequisites: 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.

- Text:
Multivariable calculus
by Brian Blank and Steven Krantz.
It is available as a paperback edition. The ISBN Number is
ISBN 1-931914-60-5
- Weekly Recitations: are organized and run by our Course Assistants (CAs)
- Question Center: The Math question center (MQC)
takes place in Science Center B10 this semester from 8:30-10:30. Its start will be announced.
- Homework: Homework is assigned each lecture and due the next
lecture. No late homework is accepted. 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.
- Computers:
There is a Mathematica project, which introduces you to
an advanced and industrial strength computer algebra system.
The use of computers and other electronic aids is not
permitted during exams although.
- Exams:
First Hourly: Wednesday, Oct 18. 2006, Hall C, 7-8:30 PM
Second Hourly: Tuesday, Nov 14, 2006, Hall B, 7-8:30 PM

- Day to day syllabus:
(*) There are a few major deviations from the book. These are
- partial differential equations, which we stress more
- parametric surfaces which we cover in more generality
- other coordinate systems are treated earlier
Otherwise, the syllabus matches quite well the book.
