Heh, when I was in my Electrical Engineering programme, I got funny looks; instead of the formulas listed, I pretty much had to just keep two straight: i = C dv/dt and v = L di/dt. Alternatively, Z = 1/Cs and Z = Ls. While everyone else was trying to keep all of their formulae with exponentials straight, I'd just solve from the base equations (either by solving the diff-eqs or equivalently the inverse Laplace transform).
