Hi, I took Calculus BC in junior year of high school, and a multivariable calculus class in senior year that covered some partial derivatives and integration but didn't go into vector calculus. I've decided to review the subject myself over winter break (and, if need be, a little into next semester). Do you guys know of any good book(s) to get a really strong Calc 1/2 basis and is also good at teaching Calc 3? I am very strong in math so a book of any difficulty level is fine as long as it teaches the subject clearly. I've heard of Spivak's for Calc 1/2. Is that a good choice? Thanks in advance.
