Looking for an "engineer's handbook".. Any suggestions? Hello, I'm looking for a book to keep on my desk that has every trig identity, important integrals, physical constants, all units and conversions, vector calculus formulas in different coordinate systems, etc. It would be nice if it also had important information relevant to electrical engineering. Can anyone recommend what I should get? I keep referring to different books for this info, and it just got annoying enough to post this message. :) Thanks for any suggestions.
