I guess I'm really wondering, when do you actually use stuff like residue theory in electrical engineering?

I suspect you need these in advanced electromagnetics mainly for physics. You definitely don't need it in undergrad, questionable even for post grad unless you specialized in EM. I studied the EM requirement for the PHD program of U of Santa Clara which is at least a middle of the road college. They don't touch any of the complex analysis other than the basic complex number calculation and formulas.

If you want to specialize in EM, then sky is the limit, if you want to study the Classical Electrodynamics by JD Jackson..........the holy grail of EM. You definitely need complex analysis, you need intro to analysis or even a little of the real analysis. But that is not for EE. For EE, if you study Intro to Electrodynamics by Griffiths and Field and Wave Electromagnetic by Cheng, you should have a reasonable foundation already.

In real life on the job, even if you are into heavy duty analog and RF design, I doubt you ever even touch this. It's like Calculus, you never use it in real life. It just give you a lot of insight how things work and give you tools for creativity.

BTW, I take it that you finished the PDE. That is a lot more important, you get to the Fourier and Laplace transforms that is absolutely necessary for a lot of the EE subjects. Even though it is not required in undergrad, I find it give me so much more insight into EM theory. Give me a much better feel of the boundary condition.

Other math subjects like basic probability and statistics are very useful if you want to study modulation and communication theory. These are quite easy subjects. I have not study these two as I have to pick and choose..........you can spend your whole life in school!!!

consider it a mathematical discipline. i was happy to take, as an engineering science elective, a course in Complex Variables from the math department. i came away from the course feeling better about the "magic" math we were using than when i went in.

every EE in signal processing should be solid with complex analysis (including contour integration and residue theory), probability and random numbers and random processes, matrix theory, approximation theory and numerical methods. besides the calculus, diff eq, and linear system theory.
