Great order and the sender was very nice. I purchased a book and got what I wanted.
No discernible marks or damage of any kind. The book is clean, looks brand new, and even smells new--as it was described.
I would highly recommend it to others who are taking similar courses. This product was delivered to me promptly, in exceptional condition, and has proven to be a crucial tool for my Differential Equations Class.
That is, it's not presenting sufficiently rigorously. As a result, reading even the easy-to-understand sections is somewhat of a chore.
I found Tenenbaum and Pollard's book rather good, well-organized, and easy to understand.you can also pick it up for $17 new. Since it lacks both rigor and expository virtue the book should largely be avoided.The book is perhaps useful as a set of problems with solutions.
Everyone I have talked to dislikes this book, although perhaps for different reasons. The book is organized in surprisingly long paragraphs and typically states in words what would be much clearler and shorter in symbols.
I have no recommendations for better books that cover numerical techniques or more advanced theory, but I'm sure other Amazon readers do. I find the style opaque because it never clearly defines its terms or states results with precision (it goes without saying that it hardly proves anything).
Others find the style opaque because it's not presented sufficiently intuitively.
Buy Ordinary Differential Equations by Morris Tenenbaum & Harry Pollard instead - an amazing book. If you're a math major, DON'T buy this book.
