Any books that are easy to understand on partial differential equations? I just came back from barnes and noble. I briefly looked at the book on partial differential equations, but it is confusing for me because it jumps to topics about partial differentiation that I didn't learn. The only experience in partial differentiation is: -partial derivatives -differentials That's about it. Not very much. So is there a book on it that covers the basics and moves onto other related topics with great explanation? I'm not very good at english, but it is the language I read.
