Putnam and Beyond

It’s a book

+ problems with infinite radicals, continued fractions and infinite powers.- no heuristics- only 5 methods of proof.

Upon first review, I see they have made some corrections from the first edition. Book came in good condition but the front cover seems to have been hastily cut near the bottom but it is negligible. Overall, I don't mind since all of the pages are perfect. I would recommend this updated version from the 2007 version since some corrections have been made.

I cant recommend this book to everyone. It is really only for a tiny percentage of students, even those who enjoy mathematics. Personally I feel like this book is catered towards the unchallenged first year undergrad, the problems sometimes require a high level of "comfortability" with abstraction and being able to wrestle with "difficult" problems.I feel as though there are books such as that of Larson's which caters to a wider audience but the beautiful problems in this book just are not matched by any other problem solving book. Seriously though, very much recommended, it will help you grow in your mathematical ability as you fight with the problems, even if you don't solve them.

very good!
