This is a fourth semester calculus course. Prerequisites are Calculus I  III or the equivalent. In particular, you should be familiar with standard techniques of differentiation and integration and with the basic properties of functions of several variables, including partial derivatives and the gradient. The last part of the course assumes some familiarity with complex numbers (although these will be reviewed) as well as Taylor series. The course begins with integration of functions of two and three variables. Next, we study the calculus of vector fields: the various differential operators (grad, curl, div) that can be applied to a function or vector field, types of integrals of vector fields (line integrals, surface integrals), and the fundamental theorems (Green, Stokes, divergence or Gauss theorem) relating differentiation and integration of vector fields. The last part of the course is an introduction to the theory of functions of a complex variable. This theory is important in many applications of mathematics, physics, and engineering, and draws upon the material of the first two thirds of the course.

Homework: There will be weekly problem sets, due at the beginning of class on Tuesdays. Problem sets will consist of problems taken from the textbook or handouts, to be written up and handed in. Homework will be collected in class on Tuesdays, or you can put it in the box on the fourth floor marked Calculus IV with my name by 5 PM of the day it is due. Graded homework will be available outside my office (605 Mathematics).
The first problem set will be due on Tuesday, January 24. You should attempt every homework problem and eventually understand how to do every problem correctly. Collaboration and discussion with your classmates is encouraged, but you must write up assignments individually.
Exams: There will be two 75minute midterm exams and a final.
Grading: The final course grade will be determined by:
Homework: 20%;
Midterm exams: 20% each;
Final exam: 40%.
Help: My office hours are Mondays and Wednesdays, 23 PM in 605 Math, and you should always feel free to make an appointment or just drop by. Help is also available without appointment in the Columbia Help Room (406 Mathematics) whenever it is open.
Academic Dishonesty: The vast majority of students do not cheat. Anyone who does so devalues the hard work of the rest of the class and creates a bad atmosphere for all. Anyone found to have cheated on an exam will receive a failing grade for the course and be subject to administrative discipline. If you are struggling with the material or have a problem about an upcoming exam, please discuss it with me instead of resorting to cheating.
