hello:
i hope i can find a website good enough on math, i am originally good at math, however, after years of abondone, i forget too much things,but recently i am working on a program that require significant math skill,even though some process streamlined by computer, but there is still manual part to deal with,and philosophy reflected from certain branch of math can not be studied merely by computer, so i hope i could find a good site for reviewing
at least including this
junior algebra like combination,permutation, complex number
trigometry
hyberbolic trigometry
calculus and differential equation
linear agebra
probability theory and accounting
number theory
set theory
graph theory
recursion theory
propositional logic
finite automata/infinite automata
what i called the good site means
content are relevant,complete,gathered,ease of navigation and study,correct,and promptly, updated,tool support is better

I don't really want to hear your oppinion who had the better theory, i just want to have a sort of comparison stating some of the different things in their theories that way i can get a good idea of what they thought. Go as detailed as you want, the more detailed the better. If anyone can get me this information it will be greatly appreciated :) THANKS!
