I took a rather disappointing multivariable calculus course this semester -- the (visiting) professor was not demanding at all. We didn't get to what is in most standard calculus III curriculum. What we did was at a nearly trivial level. I plan to take real analysis next year and don't want to be at a disadvantage in future courses so I would like to go through a multivariable text this summer.
What is a good multivariable calculus textbook with the following properties,
- is cheap or free
- has plenty of problems
- isn't an analysis text (but is above the level of stewart)
Not a textbook, but have you seen the Multivariable Calculus course offered on MIT Open Courseware? I haven't used it myself, put it looks like a pretty standard course. There are lecture notes, recorded lectures, and problem sets. If you'd rather use a textbook, you can see what book(s) are recommended there.
