need books on some math related subjects
 

Im wondering if any of you out there can tell me about some excellent books that explain algebra, trig, calc, AC and DC electricity. these are the subjects im having issues with. not so much as im bad at it, just slow.
trouble shooting "blue box" simple circuits is hard to do without speedy mental math skills on top of falling behind in class :(

(oops this is in the wrong forum :/ this was meant for general not linux general)

I always find that a good starting point for learning about things is Wikipedia. Many of the math articles there are very nicely polished and serve as a good introduction to the concepts. Related project Wikibooks has a reasonably diverse mathematics bookshelf; while they may not be up to par with academic textbooks in some regards, they have the advantage of being free :)
