I've been interested in math and physics, and I already have a pretty good list of pure math books I'm going to read. (I'm about to start Spivak's "Calculus".) However, I also want to learn about physics, so I would like some recommendations for math books that are more "computational". I'm not requesting "dumbed down" books, just ones geared more towards physics. I would specifically like books on calculus, linear algebra, and differential equations. Thank you for your help.
