So I am currently a math undergraduate (senior though) taking an introduction partial differential equations. We are using the PDE book by Farlow (Dover reprint). It seems to be a solid book though my professor does diverge from the methods used in it fairly regularly (like not making assumptions they do, utilizing newer techniques, and small stuff like different notation). I was wondering if anybody here had a recommendation on what another good intro book would be? I mainly want something that has more examples and problems to work, and a good explanation with respect to physical interpretation. Two books I found are: 1) Partial Differential Equations: Theory and Completely Solved Problems by Hillen et al. Pro: From the pages you are shown on Amazon they seem to utilize identical methods and notation as my class does. 2) Partial Differential Equations and Boundary-value Problems With Applications by Pinsky Pro: I used a book from the same series for my intro to real analysis, and I liked it. Any recommendations or comments would be appreciated.
