I'd suggest a good book over Wikipedia articles, most math articles are particularly useless for learning stuff IMO. I learned quite a lot from "Mathematics and Physics for Programmers", although I wouldn't call it perfect. I'm also quite interested in "Essential Mathematics for Games and Interactive Applications". It's true, once you've got linear algebra figured out you can do a whole lot in the simulation/games space, but it helped me to learn the more advanced stuff in terms of games and simulations.
