- Math-S21a: Multivariable Calculus
- Instructors: Daniel Goroff and Oliver Knill
- Course Assistants: Jonathan Kaplan (email@example.com) and
Izzet Coskun (firstname.lastname@example.org)
- Office hours:
Wednesday 11-12:30 for Goroff in SC-427
Mondays 11-12:30 for Knill in SC-434
Tuesdays 13-14:00 for Kaplan in SC-428b
- Website: http://www.courses.fas.harvard.edu/~maths21a/
- Time: Every Tuesday, Wednesday, and Thursday 9:30-11 except 7/4
The lectures start at 9:30 sharp.
- Place: Emerson 101 (beginning Thursday 6/27/2002)
- Problem sessions: Thursdays 1-2 in SC-110
Thursdays 8-9 in SC-112
- Homework: Weekly HW assigned in three parts, one in each lecture.
All three parts are due Tuesdays at the start of class.
No late homework is accepted. You are encouraged to
discuss solution strategies with classmates, but you
must write up answers yourself in your own words. As
with any academic work, please cite sources consulted.
- Project: As an optional 8th homework, you may choose to hand in:
- a computer laboratory project
- challenge problems you have completed
- certain projects and problems from the book
If you do decide to work on an 8th assignment, only the best 7 of
your 8 HW scores will count. Projects are due on 8/12 at 9:30 am.
Graduate students are expected to do 2/3 of the 8'th homework to get
credit for this course.
- Text: James Stewart, "Multivariable Calculus, Concepts and
Contexts" can be purchased on line or at the Harvard Coop. Student
solution manuals are also available. Please read relevant
sections of the textbook before you come to class.
- Calendar: (18 lectures in 7 weeks)

- Exams: Two Midterms
Thursday 7/11 at 9:30, in usual room.
Thursday 7/25 at 9:30, in usual room.
One cumulative Final Examination on Wednesday 8/14 at 9:15am.
These three exams are required. Please note the dates and times.
In general, we expect roughly a third of each test to consist
of True/False or Conceptional Questions directly from the text,
and another third to consist of assigned or unassigned
exercices directly from the book.
- Grades: There is a total target of T=1000 points for this course.
Roughly, we expect people who end up with over 900 points to
receive some kind of A, people who have 800-900 points to receive
some kind of B, etc. A maximum of 820 points can be obtained
during the term:
7 Homeworks, each 60 points 420 points
2 Midterms, each 200 points 400 points
If you earn N points during the term, your final exam will be worth
a possible T-N points. For example,
1) If you enter the final with all 820 points and get
50% correct on the final, your course total will be:
820 + (1000-820) * 50/100 = 910 (probably a low A or high B).
2) If you enter the final with 430 points and get
70% correct on the final, your course total will be:
430 + (1000-430) * 70/100 = 839 (probably a low B).
Notice this means you can earn back on the final any point you
miss during the term, so you always have an incentive to keep
working. This grading system is very kind to anyone who
eventually masters the material by the day of the final, but very
risky for anyone who tries to wait until then. Please keep up,
work lots of problems, go over everything you did not get right
the first time, ask lots of questions, and you will do fine.
- About this course:
- extends single variable calculus to higher dimensions;
- provides vocabulary for understanding the fundamental
equations of nature (e.g., weather, heat, planetary
motion, waves, profit maximization, quantum world);
- provides tools for describing curves, surfaces, and other
graphical objects in three dimensions;
- develops methods for solving optimization problems with and
- prepares you for further study in many other fields of
mathematics and its applications;
- improves thinking skills, problem solving skills,
visualization skills, and computing skills.
