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

 

Four exams, a few questions on each exam.  The lowest grade is dropped if all four exams are taken.  Each exam has equal weight.

Exam 1.  February 3

Exam 2.  February 26

Exam 3.  March 26

Exam 4.  April 21

There will be four homework assignments, each due the class before the corresponding exam.  Students will have a chance to present their solutions.  The homework itself will count toward the final grade.

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.

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