Hi this question is for all you math people out there. But as you will find shortly, its very specific. I'm interested in learning calculus deeply. I learned nothing in the watered down calculus that is so readily offered because of the disenchantment with "Ivory tower education". But anyways. I'm still in the process of descideing between two supposibly excellent books that treats calculus in a rigorous manner. Spivaks' Calculus and Apostals' Calculus. Did anyone have positive experiences with any of these two? What was frustrating about going through these books? Did you gain anything that you wouldn't have if you just went to traditional route to real analysis? On a side note: I noticed that all of Spivak's problems are out there in the form of a solutions manual. Can the same be said of Apostol?
