I'd like to start off by mentioning that I'm gonna begin studying Computer Science at the local polytechnic university. As I found out, the study of mathematics stops after two years. Recently I've become really interested in mathematics, especially in calculus and I don't wanna throw all my knowledge out the window just because my university doesn't put that much emphasis on pure mathematics.
So I've started a search for advanced calculus textbooks and my attention was mostly drawn by Woods' Advanced Calculus(1934),but, unfortunately, this textbook's way too expensive .
Does anyone have a suggestion on this particular matter ? Thanks !
