You should probably have a copy of the Engineer-in-training handbook. This is a tremendously useful tome as it's written to provide the tools for solving problems, as opposed to theorizing about how problems ought to be solved. So while it's 'bad' from a pure math/physics standpoint in that it invites you to take things on faith rather than learning to derive them from first principles, it's great in terms of teaching you how to apply the fruits of these disciplines.
