It's either a very good sign or a very bad sign that I'm dreaming about op-amps and RLC networks... I've been struggling to figure out how to solve them recently for my analog electronics class and I can usually get halfway through the problem and then I get stuck on something that makes no sense. No more! Thanks to dreaming about op-amps with RLC networks attached, I woke up 10 minutes ago and it all made sense. So I busted out some practice quizzes and everything works out perfectly now. Go figure.
