Textbook: Stewart, Multivariable Calculus: Early Transcendentals, UC Berkeley custom edition, 8th edition, Cengage Learning. (ISBN: 978-1-305-75645-8)

Grading: 5% HW, 15% quizzes, 20% x 2 midterms, 40% final. The bottom two HW and Quiz grades will be dropped, and the lower midterm score will be replaced by the final, if it helps. All exams will be curved. The median grade will be at least a B-. This is not an upperbound; if everyone does extremely well, I will be happy to give everyone an A+.

Exams: There will be two in-class midterm exams on Thursday, Feb 22, and Thursday, April 12. There will be no makeup exams, except for documented medical emergencies.

Quizzes will be held in section every Wednesday. They will cover material up to the preceding Thursday. The quizzes will be substantially easier than the exams, are and designed to regularly check basic understanding of the material, so that you know in case you are falling behind.

Homework will be assigned daily (problems from the textbook) on this webpage, and each week's homework will be collected the following Wednesday in section. Homework will be coarsely graded based on spot checks. You are free (and even encouraged) to talk to your classmates about the homework, but you must write up your own solutions. There is no point copying solutions from the internet since homework is mainly for your own benefit (and worth only 5%), and without working on problems you are likely to lose a lot more than that on the final.

Class Schedule

This course covers a lot of material very quickly, and in order to digest it I highly recommend reading (or even skimming) the assigned sections before lecture. The content of the course is divided into four parts:
  1. Geometric Preliminaries, Lectures 1-4.
  2. Differentiation, Lectures 5-11.
  3. Integration, Lectures 13-18.
  4. Vector Calculus Lectures 19-26.
