>>11716853Depends on what level you mean by creating, if you mean the practical engineering level of actually building shit then zero, you’ll never see ODEs ever again after college. Surely you still have to learn the theory in college but it’s just part of the learning process. Once you’re actually employed and working, even if you come across abstract math in R&D (will never happen) you will never scribble shit down with a pen and paper but use computers to do it for you through softwares like wolfram, autocad etc.
