Ordinary Differential Equations: xiii (Dover Books on Mathematics)

Good walk-through trough all the points linked to differentials, good set of knowledge remembered from seminars in secondary school and Uni.Especially precious is the point about approximating discrete solution with polynomials, to get solution in continuous domain. Priceless.

For self-study this book is amazing. Very clearly articulated and well written to a degree that it seems rare in modern text books on any subject. Found it as PDF for free, bought it anyway and haven't regretted for a second.

This book joint together the easiest way to explain the world of the differential equation and the completeness of the explanation. Despite the not so easy argument to explain is really comprehensible and complete. Very good book

A well written book on differential equations. A must-read for students who wish to master the subject. The book will appeal to students at different levels

Bought for an actuarial student in Kenya who loved it so much he stayed up all night reading it!

I am delighted with this book and with the service I received.

I must say, I really didn't expect a book issued in 70's to be so well written, and what's more, this well comprehensible. I don't consider myself to be versed in mathematics or to be a successfull decoder of mathematical formalisms. But I must say, I actually understood everything. Explanations are clear. I can't say that about more expensive alternatives such as: "Modern Introduction to Differential Equations". I also appreciate that, before you plunge into some ODE topic that requires some prerequisite, this prerequisite is placed before the actual lesson on the ODE topic.I can only recomend this book to everyone.

Awfully dry and ugly. So much huff and puff about boring details, and not enough about the real core of the subject. The problems are bad too.
