Looking for a Math book.... As the title suggests, I'm looking for a math book (or set of books). I'm not looking for a book on just one subject though. What I'm trying to find is a book that focuses on interrelationships between different ideas, particularly in analysis, but also in linear algebra. As an example, the traditional approach to teaching vector calculus involves doing green's theorem in various form in two dimensions, then Stokes's theorem, then Gauss's theorem, and then maybe in the last five pages of the book talking about differential forms, and how they're all just one theorem. What I'm looking for is something that goes in the other direction, say starting with the idea of differential forms, and showing the special case consequences of the unifying idea. Any suggestions for books that take such an approach or at least focus heavily on interconnects between mathematical ideas, especially in Analysis and Linear Algebra? Not necessarily intro books either, I'm looking for texts that offer deeper insight into the subject.
