Differential Equations and Linear Algebra

Gostei do livro. Equações diferenciais é uma das matérias mais importantes da matemática aplicada. E o preço estava em conta.

Strang's books are usually user friendly. Some topics are organized well such as differential equation system and phase diagrams. This book makes a bridge between differential equations and linear algebra. It is worth reading and studying.

I am a surgeon by profession and have been using this text in my "hobby", a serious self-study of mathematics and modern physics, in conjunction with MIT's Open Courseware and edx.org. I started off with just high school calculus from decades ago, and have made it to the mid-undergraduate maths covered in this volume. Although I'm giving it five stars, I have to add the caveat that at first it was hard to get started with this book. Professor Strang fills the text with all sorts of glimpses of more advanced topics that will be unfamiliar to new students. For example, some of the very first examples involve step and Dirac delta input, with a heavy emphasis on impulse response concepts to explain the time evolution of solutions. This really confused me at first. However, once I started to feel more familiar with ODEs, this presentation was very helpful to get me to "get it" at a deeper level than the mere methodology of finding and writing out solutions.Also, the book does not follow the OCW differential equations course (18.03) very closely, at least the version currently online, even though it supposedly grew out of a rewrite of the 18.03 syllabus. Hopefully MIT will put up an updated version of 18.03 at some point (though I do love Prof. Mattuck's lectures in the current one).I still have a decent chunk of the material ahead of me (matrix methods for ODE systems, eigenvalues, etc.) but I now find the book very easy to follow.

Simply excellent (as all of Dr. Strang's books are. As always, he presents otherwise difficult material in an intuitive fashion making itcrystal clear. I have read several of his books on linear algebra and computational science and found the presentation of thecalculus involved in differential equations to be an excellent addition to his previous material on linear algebra. This is a book that should be read (even if one has read several booksbefore on related topics (as I have).The video presentations available at ocw.mit.edu are a valuable addition to the book.

I always appreciated Gilbert Strang style of teaching watching his video lectures at MIT.ocw. When this book came out I was curious how he would be able to translate his effective teaching methods into the writing. After half of the book, I can say this is an high-quality book that explains concisely, clearly and easily differential equations and linear algebra. Often, the equations and reasonings are surrounded with real and practical example which further clearify the concepts previously illustrated. FIVE STARS
