There was a moment in, I believe, my diff eq course where the relationship between derivatives/integrals and the Laplace & Fourier transforms suddenly became crystal clear. That wasn't what the lecture was even about, but from that point on everything got a lot easier to understand. I'd taken two or three EE courses where we bounced back and forth between the time domain and frequency domain, and diff eq was my fourth calculus class, so both topics were already quite familiar to me, but groking the relationship between them made everything so clear.
