A First Course in Differential Equations with Modeling Applications, International Metric Edition

This is the wrong book

Bonjour, le problème que le livre n'est pas neuf. Que j'ai pas aimé

This is a very good book for those who know already differential equations and may want to use it to brush up on applications.If you need to use it as a text book and if you have a good professor that explain concepts well, this book may be useful as a reference and supplemental material.But if you are trying to learn differential equations on your own, using this book will prove to be a huge challenge.It suffers from the same issue like many other text books: it is written for those who already know the materials.At the beginning of every chapter there are presented theoretical concepts in a very dense and hard to understand manner. Then the few examples that follow are not wisely chosen. Instead of choosing one simple example that highlights exactly what was just presented, they give some confusing and complicated examples that are a challenge to solve on their own without the new concepts. Another issue I found is that many examples are not worked out completely and don't show all the steps involved on solving which assumes that the reader already knows those concepts.Finally, one of the most annoying things is when the author points back one or two chapters to a specific exercise and continues with some concepts just introduced but without writing again that previous exercise, so one doesn't know what they are talking about without going back to find that specific page.Overall I found this book hard to follow, fragmented and all around frustrating. Some people are good at math, but not good at teaching math.I suffered through this book for a while, but finally I bought the two volumes of Differential & Integral Calculus by Courant and I find myself flipping though them to get the gist of what this book attempts to teach.

This is for book only, even though the description talks about access to WebAssign, etc. You will need to buy it separately at the Cengage website for about $68.

I'm taking Diff Eq for the first time, online. The professor hasn't transitioned to online well, so I'm mostly having to teach myself. This text has shown not to be the best when it comes to explaining things conceptually. It is notation heavy, and the examples are overly complicated and hard to follow. If I wasn't forced to buy this book for homework, I would be just fine using online videos and other non-assigned books.
