Math Camp for Economist help!

I'm basically teaching myself how to do pass an PhD economics placement test, and I'm looking for resources to learn these things that aren't books.

I have A LOT of books, including the math camp notes for my school which I am currently unable to attend. But I'm looking for either video collections or forums to discuss these things and ask questions. We're using the book, Further Mathematics for Economic Analysis and I find it really useful. (I'm in a related social science program and looking to take econ classes down the line).

I need to know how to do basic real analysis proofs, log-linearize some functions, tell if a formula is homogenous, homothetic, etc. Thanks!

Khan Academy, maybe? You don't have to sign in to look around. Just click on Subjects in the upper left corner.

MathOverflow seems to be a spot with real mathematicians and grad students. I'd do a lot of reading and research prior to asking questions.

WolframAlpha is also a good source for math-related topics.

You want Math Stackexchange, not MathOverflow, which is strictly limited to "research-related" questions (whatever that actually means; in any case, you occasionally see prominent mathematicians get questions deleted for being off-topic; the infamous chalk question would never stand now). Math Stackexchange definitely will address basic real analysis and the other stuff is in bounds. There's a statistics stackexchange which might be good for some of this stuff.

This is a great little review of some serious math: Fundamentals of Scientific Mathematics, by George Owen (Dover ppbk), 274pp. Reviews functions, matrices, geometry, analytic geometry, linear algebra, basic calculus. I think it's at the level you want.

Also, Mathematics for economists, by E Roy Weintraub (Cambridge Univ.), 180pp, might be about right.

Sorry, missed the web/video only bit. Jeez I'm old fashioned.
