Hi, I have finished my bachelors in electrical engineering and now I will continue with masters in the same area, specifically in telecommunications/signal processing branch. I would not consider my mathematical background too weak, I have good knowledge of calculus and linear algebra. In the last semester of my bachelors, I took an abstract math class, number theory, and I quite liked it though it felt much harder for me in comparison to other classes like calculus, linear algebra and discrete math. So, what would be the way to go now? I know that for telecommunications, I would probably need more numerical linear algebra, also maybe it would be a good idea to develop my calculus skills. I have also interest in it more abstract math, as I said, but I think for now, trying to properly learn analysis or abstract algebra would divert me from my actual focus, which is of course electrical engineering, in which pure math has barely any place. On the other hand, the process of learning abstract math would enhance my way of thinking and advance my toolbox in some other way. Do you think I could learn at least some basic pure math stuff in the time remaining from my engineering studies? Could anyone provide some motivation for that? Thanks a lot.
