Do you trust mathematical materials on Wikipedia?
I trust most of them to not be wrong, but I don't trust them to be right. Mathematical concepts are bit like binary search -- getting the flavor right isn't that difficult, but being concise, complete, and correct is very difficult even for experts. In non-mathematics books that I've read (econometrics, operations research, etc.), some of the bits of exposition on fundamentals (multi-var calc, stats/probability, etc.) are not wrong but not quite right. For lay purposes, wikipedia is probably fine, and any resource *that people use* that makes an effort to educate and inform on mathematical concepts deserves some thanks and support.
