Specifically I'm looking at linear algebra, which topics in a first course of that class is useful to an electrical engineer. I'm taking the class right now and it feels like all the useful stuff (solving equations, matrix manipulation, etc) I already knew prior to this class. All the other stuff seems more theoretical and I'm wondering if these topics are ever used in EE. Not that I mind either way, I took the class because I enjoy math not because I thought it might be useful. The same goes for Complex analysis, I work with complex numbers often but never anything fancy (simple algebraic manipulation usually). Will I gain anything useful to EE by taking the class. I'm talking mostly about undergraduate level for everything, I am interested in graduate EE work because I'm still undecided whether I wish to go but I'm specifically wondering about my short term.
