Partial differential equation textbook with physics applications

[Aroldo]

Hi everyone,
First of all, this is an awesome place :)
I'm looking for a differential equation book, with partial differential equation (and Fourier series solution) that really goes into physics.
I'm a 3-year undergrad student in Physics so I already know a little about it.
By the way, for now my favorite subject is electrodynamics.

I'd like to help you, I have an excellent book, but it's on Croatian language... :(Try with something like this: http://www.sciencedirect.com/science/book/9780123869111
