I did my engineering course (given by the Mathematics department) on DEs a long time ago, and all I remember is the phrase "taking the D operator". Where you take it, I can't remember ... out the front of the equation, I believe. Anyway, it was so unrelated to anything we were doing in the rest of the course that sadly, we never used any of it.
In fact, our electrical engineering lecturers effectively taught us what DE solving we needed to know using other methods. This led to strange anachronisms such as in 3rd year we were taking a mathematics class for solving the wave equation in two dimensions - on the first day I asked the lecturer if we would be looking at three dimensions, because we were already solving DEs in those situations for electromagnetic wave propagation in waveguides.
Looking back on it all, I think we were being taught certain things just so the university administrators could tick an accreditation box somewhere saying "Yes, we've taught them how to solve DEs", but there was little or no thought towards how to teach the subjects in an integrated way (pardon the pun).
