Hi, I'll be taking Quantum Mechanics A, Electromagnetic Theory I and PDE next semester. However, in the course description, PDE is a corequisite for QM and Electromagnetic. I wanted to know what PDE topic should I read up on during the holiday that i might encounter in QM or EM before the actual PDE course. Well, actually i wanted to know all the PDE topics that will be used in QM and EM before the semester start. I think it's easier to learn physics if you take care of the math first. btw, QM and EM classes use David Griffin's book, Introduction to Quantum Mechanics and Introduction to Electrodynamics. thanks!
