Hi all, I'm a graduating senior and I'm interested in covering and recovering mathematics to the calculus level. I've been feeling that all of my math courses to this point, high school and before, haven't really taught me much of anything in the way of real mathematics. I was looking for some recommended reading that would cover precalculus topics, such as algebra and trig, and some lower level calculus. I've heard good things about Gelfand's Trigonometry and perhaps Algebra as well, but not much outside of that. Any help?
