I just finished doing pre calculus and I was eager to get started with calculus so I started to read apostol however the book happens to be somewhat dificult for me. It begins proving the exaustation method of Archimedes, and with other subjects, I prefered to start with my brother's high school calculus book which is way easier. I wonder which books should I get for advanced calculus and analysis. Is apostol v2 advanced calculus? I also have mcgraw hill schaums outline of advanced calculus which is 442 pages. I d like to read as less books as possible, In order to have more time to study more advanced math. Im considering to read as fast as I can the high school calculus book, then to try schaums outline of advanced calculus and then apostol s analysis. but it 'd make me feel bad not to read apostol v1 and v2 a lot. Any advices about which study plan to follow?
