Hello all, I'm simply a student who has a passion for mathematics. I'm just curious as what domain of mathematics I should study next. I'm a university student who plans on persuing an electrical engineering degree. I've already learnt Calculus 1&2 along with linear algebra. What would be the next level of mathematics after things such as calculus 2 or even advancements in what I've already learnt in linear algebra? Thanks in advance!
