Complex Variable and Applications (math. 3160)
Spring 2018
The imaginary number is a fine and wonderful recourse
of the divine spirit, almost an amphibian between being
and not being.
--Gottfried Whilhem Leibniz |
The shortest path between two truths in the real
domain passes through the complex domain.
-- Jacques Hadamard |
The complexity of the complex variable course is more
imaginary than real.
-- An encouraging observation |
"The number you have dialed is imaginary. Please
rotate your phone 90 degrees and try again."
-- A math joke

Policy:
Exercises: Problems are typical of what you'll be asked
on exams.
Calculator: A calculator is not required for the
course, although it may be useful for some homework problems.
Calculators will be forbidden in exams.
Final exam: Half of the final will be devoted to
material covered after the second midquarter exam. The rest will
be comprehensive. Students must take the final to pass the
course.
Grades: The final grade will be based on the
following score: Two midterm exams (50%= 25%+25%) +
homework(20%) + final (30%).

physical, sensory, cognitive, systemic, learning and psychiatric
disabilities. Please contact me at the beginning of the quarter
to discuss any such accommodations for the course.
Homework problems - to be posted (pages and numbers corresponds
to 8th edition of the Churchill and Brown text)
The only way to learn mathematics is to do mathematics.
