This book has, hands down, the worst explanations of any textbook I have ever read. During my second semester of calculus I just gave up reading the text and started relying solely on lecture. Also, half this book is fluff; such as the pointlessly short chapter on differential equations and all the chapters on applications(natural sciences, statistics etc.) Those things should be left to other books that can go into more detail. No course even has the time to cover all those topics. Important chapters, like methods for integration, are far too short(there is one stinking page for trigonometric substitution). The only redeeming factors of this book is that it has lots of color illustrations, and that it's massive enough to beat someone to death with.
