Introduction: Calculus is a powerful mathematical tool which has proven to be of profound practical use in the sciences and one of the great achievements of human thought.
But you know that already.
The theory of calculus with complex numbers, also known as the theory of functions of a complex variable, is significantly richer than just the extension of calculus to the real plane. The beautiful underlying algebraic and geometric structure of the complex numbers allows us to describe a large class of extremely well-behaved and physically-relevant functions with a very small number of conditions and allows us to better understand functions of a real variable. It's an exciting twist on a well-known story, and will quite possibly answer many questions you never knew you had.
This course is an introduction to complex analysis, intended primarily for engineering students. Some attention will be paid to theory but mainly this course will be focused on developing your ability to work in the realm of calculus with complex numbers.
