Hi all, I've been looking and searching around for a good book for some pre-calculus review, and decided on one of Sheldon Axler's books. Looking at his site and the contents of both books (links below), I'm not sure what the difference is between them, other than some re-ordering of things in the newer "Precaculus.." book. In fact, the "Algebra & Trigonometry" book seems if anything to have a bit more, which is a tad confusing. Maybe the newer "Precalculus.." books has corrections, better layout, etc.? Anyone use any or have any opinion on which to get? Check them out below. Besides the marketing reasons, why would anyone get the "Precalculus.." over "Algebra & Trigonometry"? http://algebratrig.axler.net vs. http://precalculus.axler.net Thanks!
