Hey again, I just posted a thread yesterday about University preparation and I was recommended to consolidate and expand my calculus knowledge and in light of that I would like help in choosing a calculus book; While looking at these forums there's been alot of praise for Michael Spivak's book "Calculus", but i'm not sure if it's at the right level for me; I've already studied derivatives, differentiation and simple integrals, as well as differentiating/integrating trigonometric functions and differentiation/integration of e. After looking at the index on Amazon of the book, it seems to me that the book spends almost 1/2 to 2/3 of the book on these things, which I feel relativity confident on. Therefore do you think it's worth me buying this book? Is there sufficient detail in it to warrant me buying it? To be honest the price is not a HUGE issue as it's Christmas anyway and since i'm usually given some money a good calculus book would be good (i know that sounds sad =P) and a good investment. If this book isn't right could you please recommend on that would be more suitable? Thanks alot again.
