Course Description: The purpose of this course is to learn about the theory of functions of a complex variable and the applications of this theory.

The course will follow the text rather closely. But it is strongly advised to attend class, as the instructor will offer many ideas and insights not to be found in the book. It is also important to keep up with the homework.

Work Required in the Course: There will be weekly homework assignments.

The relative weights of the course components are as follows:

Homework: 20%

Midterm I: 40%

Midterm II: 40%

TOTAL: 100%


If you are taking the course Pass/Fail, then the cutoff for a pass is C - or 65 percent.
