5.0 out of 5 stars
a great book for its target audience, July 27, 2004
Some reviewers have been puzzled as to the style of this book, deep mathematics for the unsophisticated reader. This is explained by its origin in the 1960's when many bright high school students were not offered calculus until college. Hence some top colleges experimented with very high level introductions to calculus aimed at gifted and committed students who had never seen calculus. Possibly Spivak took such a course, but certainly his book was used as the text for one at Harvard, and was still used more recently at a few schools still offering this course, such as University of Chicago.
Unfortunately today, due to the somewhat misguided AP movement, which is oriented to standardized test performance rather than understanding, almost all mathematically talented high school students take calculus before college, receiving significantly inferior preparation to what they would receive in college. The result is that many top colleges where the Spivak type course originated, no longer see the need to offer it.
This means that gifted freshmen at schools such as Harvard and Stanford are now asked to begin with an advanced honors calculus course for which Spivak is the ideal prerecquisite, although those same schools do not offer that prerecquisite. Thus if you are a high school student hoping to become a mathematician and planning to attend many elite colleges, almost the only way to be adequately prepared for an honors level mathematics program is to read this book first. It may be that a book like Stewart or even Calculus Made Easy, is useful as a first introduction to calculus, but it will not get you to the level you need for a course out of Apostol vol. 2, or Loomis and Sternberg.
Although some seasoned mathematicians eventually come to prefer other treatments such as those of Apostol or Courant, the appeal for a young student of Spivak's light hearted, clear, and enthusiastic presentation is probably unmatched by any other work. For forty years there has been a cult of fanatical adherents to the books of Spivak, and they still deliver the goods to the audience for which they are intended.
There is only one caveat that may even be unimportant for beginners, but it is that Spivak is almost too clear and thorough in his explanations. I.e. a future researcher needs to learn to question, to discover and work things out on his own, whereas Spivak explains everything for you. So every now and then resist reading his explanation and try working out a proof or a generalization on your own, and see if it doesn't become even clearer afterwards. Understanding how a proof was thought of is different from just knowing how it goes.

Bridge to Real Analysis, February 25, 2001
I agree with some of the previous reviewers that Spivak's book is a bit much for any but the brightest first-year calculus students. It would be quite the uncommon 17-18 year old who's disciplined and mature enough to rise to the challenge. Maybe with the guidance of an outstanding lecturer...On the other hand, Spivak serves as excellent preparation for one's first real analysis course: ideally, read through this book (and, crucially, do ALL the exercises) the summer before introductory analysis, and you'll be in great shape to tackle the likes of Rudin's "Principles of Mathematical Analysis." In the process, you'll also build a much deeper understanding and appreciation of the material covered in first-year calculus. Spivak's book is also a wonderful re-introduction to mathematics for those who've been away for a while. It's very well suited to independent study, and Spivak is an excellent teacher. The book is carefully written, chatty but not informal, conversational but not overly long-winded. The exercises are challenging, but provide additional insight into the material and, more importantly, deepen your understanding and build your problem-solving and proof-writing skills. With patience and diligence they're all quite solvable by anyone who has, or who is serious about cultivating, a little mathematical maturity.

Superb for self-study (with answer book), August 3, 2003
By A Customer
Calculus wasn't taught in public high schools 50 years ago -- our brains were thought too soft to encounter it under the age of 18. The 17 year old supermarket checkout girl where I live in rural New York will take it this fall. I've always been fascinated with math, particularly the inevitability of it all (how mathematicians were dragged kicking and screaming into imaginary numbers, non-Euclidean geomtery and the completed infinite). Despite minimal background, I was able to get A's in calculus, differential equations, and complex variables at Princeton back then. It was like my Bar Mitzvah, getting through by mumbling incantations in a language I didn't understand. Figuring that I'd received a decent mathematical background, I tried studying math at a higher level 5 years ago when I left medical practice. Strichartz was dense and I spent hours puzzling over notation in the first edition (until I found that some of the most confusing parts were actually errors not all of which were corrected in the second paperback edition). I made it about half way through -- it just seemed too abstract. Abbott's book was also quite good, but again pure analysis is about the logical structure underneath mathematics (something I certainly was trying to understand). Having read the rave reviews of Spivak's book in this forum, I bought it (along with the answer book), and have spent the last 8 months going through it, and doing about 3/4 of the problems. It is marvellous. The exposition is clear and friendly (as are Strichartz and Abbott) -- something not seen in the math books of the 50s (although Spivak's first edition goes back to 1968). Almost nothing is assumed (except the properties of the rational numbers). Everything is derived from them and clearly (including one construction of the real numbers from the rational numbers at the end and (typically) two more constructions of the reals in the problems at the end of that chapter). Even better -- the book doesn't just show you how mathematical consequences follow logically from inscrutible definitions. It shows you why the definitions must be the way they are. The chapter on the definitions and properties of the logarithmic and the exponential functions is aparticularly fine example of this technique and of Spivak's teaching style. One does not study human anatomy by studying only the bones which hold up the physical structure, although without bones we are a just pile of goo. To learn anatomy one must also study the flesh draped on the (physical/logical) skeleton. This is also where Spivak excels. There are plenty of examples sprinkled throughout the text in addition to the logical structure -- several whole chapters are devoted to applications of the theory just developed. The real mathematical flesh is in the exercises. None of them are trivial. None are of the 'plug and chug' variety seen in Thomas-- which amazingly is still out there -- it was my text in 1956. They are best described as 'blink and think'. I don't think it would be possible to use the book for self-study with no teacher to talk to without getting the answer book. Spivak supplies answers and/or hints to only about 10% of the problems. The answer book does the rest (although I think it does contain a few typos). The book would have been very difficult to use as a Freshman, with no calculus exposure while taking physics at the same time (which most of us did back then). Derivatives aren't introduced for a long time, and integrals even later. The Freshman physics course started right off with Newton's laws (this was John Wheeler after all). However, once Spivak gets you to derivatives and integrals you will understand them, rather than just mouthing formulas. Spivak certainly isn't the only analysis book you'll need. Both Strichartz and Abbott go a lot farther. The book contains nothing about Fourier series or higher dimensions. However, Spivak is certainly the place to start if you want to understand "what's going on under the hood" as another reviewer put it. Hopefully I'll now be able to re-read Strichartz and Abbott having seen and pondered the mathematical flesh which is draped on the logical bones these two books discuss.
