**Welcome** to the magical world of multivariable calculus! Multivariable calculus is better than chocolate,
the internet, and love. It is also better than single variable calculus, which is not better than love.

**Philosophy:** My lectures will
aim to be minimalistic but comprehensive -- I'll try to emphasize methods that encompass other ones
and then go straight to examples, rather than focusing on many "special case" methods
that you can learn from the text. I will only deviate from the text to make things easier
for you to remember or tie together. The first week will be heavily
focused on terminology, because in the past my students have said this was extremely helpful.

**Lecture vs. discussion:** I won't be adhering to a strict division between lecture and discussion time. To prevent insanity, some breaks will be inserted.

**Reading:** Take advantage of being a human! Understand things to help you
memorize them, *and* memorize things to help you understand them. You have an unconscious
brain that learns -- on __the night before__ each lecture, I expect everyone to read (not necessarily understand)
the upcomming text sections completely, focussing on key terminology so you can process
the material faster when I introduce it. Fifteen minutes is enough for that; there's no need to overdo it, but definitely do it!

**Participation:** This means classroom involvement, attendance, and coming to office hours; participation marks will
not be awarded generously! Please __use your face__ in class: if you get it, nod your head; if it's so easy
you're bored, nod faster;
if you don't get it, look unhappy somehow.

Your __attendance will be inferred__ when work is handed back and when you take quizzes. After
receiveing a failed quiz/exam, please
__attend the very next office hours__; I'll keep a record of this. Email is not practical for
math questions, but will be used for announcements, so you are all
expected to check the email you have registered on bearfacts.berkeley.edu.

**Quizzes** will usually be on Tuesdays and Fridays,
except for on exam days. There won't
be any makeup quizzes, but I'll drop your lowest two quiz scores.
The quizzes should help make sure that you keep up with
the material. Later parts of the course depend heavily on the earlier
parts, so it can be hard to catch up if you fall behind!

**Homework** assignments must be submitted at the beginning of the lecture
when they are due; this is partially to prevent students working on homework during lecture.
Late homework will not be accepted. Homework is graded out of 20, with
10 points for completeness, and 10 points for two randomly selected problems.

You may check your answers to odd-numbered problems
in the back of the book, but you need to turn in solutions, not just
answers. Plagiarizing solutions from the internet, etc., will result in a negative grade
for that assignment.
You are __encouraged__ to discuss the homework problems with your
classmates, but you must write your solutions on your own. This is partially to prevent you
developing a __false sense of comfort__ and not realizing you can't do it until the exam.

Finally, to avoid making the grader miserable, __5 points will be deducted__ for violating
any of the following easy-to-follow homework policies:

- The front page must have the assigned text-section numbers, your name and your
student number written clearly at the
__top right__. - The front page must also show a list of all the assigned problem numbers, and
you must
__circle__the problem numbers you have omitted. So, you may wish to design a cover-page template where you can copy/paste problem lists from the web. - Homework problems must be presented
__in order__, including omitted problems with the word "OMITTED" in place of a solution. - The homework must be stapled at the
__top left__, and the stapling should not cover any of your work. So, avoid writing at the top left, and if you expect to be forgetful with stapling, buy a small stapler to keep with you at all times.

**Exams:** There will be two midterms, a final, and no makeup exams
(see the grading scheme below, however). Irrespective of grades, missing
the final will result in __automatic failure__ of the course. Please
check the date now to make sure that you can attend the final!

Calculators and notes will NOT be allowed for the exams. There won't be that much to memorize: around one
or two key formulas per lecture, at most. You should review and be familiar with the integration techniques
covered in Math 1B. To obtain full credit for an exam question, you must obtain the
correct answer, __put a box around it__ (otherwise box your piece of work closest to an answer)
, and give a correct and readable derivation or justification of the answer. Unjustified correct
answers will be regarded very suspiciously and will receive little or
no credit. To maximize credit, __cross out incorrect
work__. Grades will almost never be changed for "subjective" reasons,
for the sake of consistency, but grades will be explained at request.

**Disabled students**
requiring accommodations for exams must submit to the
instructor a "letter of accommodation" from the Disabled Students
Program two weeks in advance.

**Grades** will be calculated as follows, with the lowest of the first four 20%'s dropped:

- Classwork: 20% (Participation 10% + Quizzes 15%, with lowest 5% dropped)
- Homework: 20%
- Midterm Exam 1: 20%
- Midterm Exam 2: 20%
- Final Exam: 40%

I don't intend to "curve" any grades (except in the unlikely event that the median is above 85% or below 55%, in which case some adjustment may be necessary). This means it is more than worth your while to interact with each other and help each other learn as much as possible: you can all get high grades together! It also means I will do my best to give evaluations that are fair and seemingly feasible to past students.

**Incomplete grades**, according to university policy, can be given
only if *unantipicated events beyond your control* (e.g. a
medical emergency) make it impossible for you to complete the course,
*and if you are otherwise passing* (with a C or above).
