I don't use, and barely passed that circuits course using partial differential equations. But at least now I have some idea of what they are, and where they are useful. I also don't use Fourier transforms much, or Taylor or McLaurin expansions - but it gives me a solid foundation for understanding how people do various signal analysis, function approximation, etc. I.e. I agree that I had to take a lot of math. And I don't use much of it. But I'm not really resentful of it - I'm only resentful of the sometimes useless profs we got.
