دانلود کتاب Ordinary differential equations

To begin my graduate level Advanced Differential Equations course, the professor introduced this text as “The Yellow Book of Death.” Quite an accurate description. The consenus around the Math department is that it is a horrible book. The text is very unclear at many steps, and leaves out other key steps. I rarely, if ever, use this text to study for Differential Equations, as the notes given by the professor are much clearer. Being that this book is never used, it is nothing more than a yellow eyesore on my bookshelf. Today, I am to take the comprehensive exam for my Master’s in Mathematics and this text has not been of any use in preparation for the exam. Upon the conclusion of this exam, I fully intend to take this book out to a field and shoot it. I am going to end this source of anger and frustration with a 9mm bullet.
