Textbook:  Complex Variable and Applications   9th edition

                    Brown and Churchill

 

Complex analysis is not only of use in other branches of mathematics, but also in various fields of engineering. The course, like calculus, concerns functions of a single variable and covers limits, derivatives, integrals, and series. However, because the variable is a complex number, rather than a real number, the subject has a completely different flavor than calculus – in my opinion simpler and more elegant.

Grades

Three exams, each worth 30%

     Exam 1.  September 

     Exam 2.  November 

     Exam 3.  December 

Five homework assignments, each worth 2%.

The exams will be graded on a sliding scale, the harder the exam, the more lenient the  grading.  Out of 100, it will never be stricter than 90A, 80B, 70C, 60D.

Homework will receive full credit if there is an honest attempt to do the problems.

Exam and homework grades will be posted on the canvas Grades section within a week, but usually sooner.
