Last year I took ap calculus ab, and im taking ap calculus bc next year. So i decided to refresh my memory this summer and went through The Calculus Lifesaver by Adrian Banner, and thoroughly enjoyed it since i didn't get the depth that it went into in class. Now i know there are more "in depth" books out there, specifically Apostol and Spivak.

I read what I could of them online, which was only like a couple of pages, and liked Apostol's approach a little better, but could someone lead me towards which one will give me a true understanding of calculus? I love a challenge, there would defiantly have to be problems-solutions, good explanations of proofs, theorems, defiantly have to cover calculus AB and BC, and really overall just give me that true mathematical understanding I'm looking for.

 Recognitions: Gold Member Tom Apostol's generally is the tougher to read among those two. But you can't go wrong with either one. I'm going through Spivak's right now, and I'm loving it. Spivak's IMO is more enjoyable to read, Apostol's is a bit dry but I guess it's alright for serious students. In short, they're pretty much interchangeable.
 I agree with thrill3rnit3 about the two books being interchangeable. If you go through either book, you will be getting the best education in calculus you can get through a textbook in my opinion. I wish I had known about either of these books when I was first learning calculus. If you liked Apostol, don't be afraid to go with it, and you will definitely learn calculus thoroughly. I think he covers quite a bit more material than Spivak, although I believe there is an answer book for Spivak, which could be helpful for self-study. In answer to your question, they definitely cover calculus for AB, BC, and beyond. These books can be expensive, especially Apostol, so be sure to see if your library has them or if you could get them through inter-library loan. I thought I should mention that there is a third calculus book to complete the tribunal, and that is Differential and Integral Calculus by Richard Courant. It is a more intuitive and physical approach than the above two books. There is a newer version called Introduction to Calculus and Analysis that was supposed to be developed to fit the American calculus course better. Spivak and Apostol have much more rigor though.

The most important thing in going through either book (especially Spivak's) is to do ALL or MOST of the exercises.
 Thanks to both of you, but i still have one more question... Im assuming then that apostol's book doesn't have answers to his exercises then?
 Recognitions: Gold Member Spivak's doesn't edit: actually he has answers to SELECTED problems
 Yes, Spivak has answers only to selected exercises in the back of his book. But, there is a totally separate answer book that has actual solutions or hints to all the exercises. I looked at Apostol again, and he does have answers (not solutions) to almost all of his exercises. The only ones he doesn't include in the back are the proof-like questions. Apostol is very expensive, so you might want to look at getting Spivak and his answer book, which looks like it would cost you less than if you got Apostol's book. I've never really read through Spivak, but looking at it some more, it looks very, very good. It's unfortunate that Apostol is so expensive, as it is very good as well. It's a no lose situation.
 Recognitions: Gold Member There are international versions available at Alibris.com that sells for about $22 each. http://www.alibris.com/booksearch.de...4742937&cart=1 I think these versions are paperback and are made of cheaper quality. Do you think it's a good bargain (because I'm planning to get one)??

Considering last time I checked Apostol was closer to $100 so it seems like a fairly good deal.  Recognitions: Gold Member yeah but it's paperback and the printing would probably be a little bad  Quote by thrill3rnit3 There are international versions available at Alibris.com that sells for about$22 each. http://www.alibris.com/booksearch.de...4742937&cart=1 I think these versions are paperback and are made of cheaper quality.

Yea, they are definitely paperback, but I'm not for sure of the quality. I know a lot of people swear by ordering the international editions, so they can't be that bad. I think they're more like nice photocopies than actual printings though. I myself strongly prefer hardback, and I must admit that I've seen a hardback Apostol in the library, which was an extremely nice book. The book is very well bound and is heavy because of the quality paper. The book is rather thick though, so the paperback may not hold up as long. I guess you could get the paperback, and then if you really do enjoy the book, then splurge for the nicer hardback, as it is definitely a nice looking book on the desk or bookshelf.

 Quote by thrill3rnit3 yeah but it's paperback and the printing would probably be a little bad
I have an International edition of Apostol (I'm assuming it's the same as the publishers are identical) so I thought I would shed some light on the issue of the quality of the international edition of Apostol since some people seem to be worried about it. It's indeed paperback and the cover is uniformly colored, but the coloring is pretty bad so you will probably get these white lines all over it after just a little use. If you want something that looks impressive on the desk, then this isn't it. As with all international edition the pages are pretty thin, but they seem to be sufficiently thick to keep them from breaking (I haven't had a single tear in either of the volumes and I wouldn't consider myself especially careful). Personally I prefer these slightly thinner pages as they are easier to handle than the photo-like paper in some modern textbooks (especially science books). The binding also seems quite solid. As for the actual printing it seems fine. Every 20 or so pages a single letter is a little blurry, but easily readable, and sometimes the text becomes a bit bolder in what seems to be arbitrary places, but in my opinion it isn't a problem.

As for which book is actually the best I believe both can give you an excellent handle of calculus. Personally I find Apostol hard to learn from and his reasoning often seem unsupported in my opinion, but it contains all the material and if you are willing to spend a little extra time deciphering proofs and why they are structured as they are then Apostol can be a good book, and it may actually force you to think a bit more deeply about the material. Spivak is pretty talkative which can be an obstacle to some students who have a hard time extracting rigorous arguments or mathematical heuristics from such text, but personally if I were to re-learn calculus I would go with Spivak over Apostol.

I don't know how much alibris charges for shipping, but if you want to save 10-20$you may want to take a look at AbeBooks. There they sell for about 3$, but the shipping seems awfully expensive so I don't know if it really is cheaper in total. AbeBooks is usually pretty reliable (just remember to order a new book and not a used one), though I have once received the wrong book (ordered An Introduction to Homological Algebra, but got An Introduction to Harmonic Analysis).

 Quote by rasmhop AbeBooks is usually pretty reliable.
I have also had good experience with AbeBooks. Thanks for the extra advice. I would really like to have time to go through either of these books for enjoyment and picking up a few things. I'm impressed by Fisicks being aware of these books and willing to go through them, while only in high school.
 Recognitions: Gold Member abebooks is wonderful site, thanks for sharing They sell volume 1 (international version) for about 3 dollars. Should I trust that? EDIT: nevermind, shipping for 2 (international) books is a whopping 57 dollars!!!
 Sorry to confuse you more on the issue, but I thought I'd throw another book into the pot (aweful metaphor I admit!). The book by Courant and John Introduction to Calculus and Analysis I found was very good, at the same level as Spivak, but a very nice read, well explained. Spivak, however, is something of an institution, or rather, a religion these days. So there you are, not sure I helped any.
 Recognitions: Gold Member The books by Spivak, Apostol, and Courant are pretty much the "big three". You can't go wrong with either one of them.

You're right, as Courant is very good. This also includes his original book, Differential and Integral Calculus. Although, I had already mentioned Courant back in the 3rd post. :)
