 Text: The book
"Multivariable Calculus: Concepts and Contexts"
by James Stewart is recommended in addition to
following the lectures. Both the newest edition or
the older edition are ok. Homework will be distributed
in each class and not assigned from the book.
 About this course:
 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,
computergraphics, 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;
 Homework: Weekly HW will be assigned in three parts,
one in each lecture. You will receive a handout for
each problem set. Problems will not be assigned
from books.
 Quizes: We will have three short online multiple choice quizes.
The quizes do not enter the grade directly but allow to weight
the quiz score better. More details below.
 Computers: The use of computers and other
electronic aids is not permitted during exams.
Mathematica projects are optional and will
teach you the basics of a computer algebra system.
Harvard has a site licence for Mathematica. Using
this software does not lead to any additional expenses.
The total time for doing the lab is 13 hours.
For people who prefer not to use any computers, there
will be the possibility to work on some challenge problems or
to write a little paper on your own. As experience has
shown, the later options require much more time resources
but they can be rewarding too. The project will be handed
in during the last lecture.
 Graduate Credit: This course can be taken for graduate credit.
The course work is the same. To fulfill the graduate credit,
a minimal 2/3 score has to be reached for the final project
and all three quizes have to be completed. The project can
also be chosen by the student.
 Exams:
Two midterm exams and one final exam. The midterms
will be administered during class time in the usual lecture hall.
The final will take place during the examination period.
Online quizes are offered during nonexamination weeks 1,2,4,6.
They are "light", are of multiple choice nature and will help you to
gauge your progress in knowing the basic concepts. The score in
the quizzes will allow you to balance the scores in the midterms.
 Grades:
First and second hourly 40 % weighted according to quizz
Homework 25 %
Project 5 %
Final 30 %
The higherscoring midterm will be worth 20+X%, the other midterm
will be worth 20X%, where X is the total score in the online quizzes
scaled from 0 to 8. If the grade on the final exam is higher than
the grade from the composite score, then the final grade for the
course will be equal to the grade on the final exam. Active class
participation and attendence can boost your final grade by up to 5%.
 Calendar: we have 21 sessions: 19 lectures plus 2 midterms
during 7 weeks from June 28, 2005 to August 11, 2005. This is
followed by a final examination week ending August 19. You might
