'cause I don't remember stuff from multivar. calc (or even calc for that matter), and doing this stuff is getting to be a pain without more basic knowledge.
::pokes people:: Any suggested calc reviews/tutorials for me to skim out there? Textbooks are fine as well, but they'll have to be good. Amazon usually had older versions for something I can afford, but it'll take time for it to get to me, so websites are still preferable.
