Unfortunately this book severely lacks step by step examples and makes many assumptions about what the reader does and does not know. I know calculus but most of the steps in the example problems are skipped over. Each chapter is divided into four or five sections but each chapter is only around ten pages long. This means that an entire section of knowledge is crammed into two pages. Add in that half of a page is usually used for a picture and you end up with a book full of theorems but lacking in substance. These aren't even formulas per say but instead are chapters filled with starting points. To elaborate about how bad this book is; I bought a study guide which has more full detailed step-by-step answers than this book. In fact the "full answers" in the back generally consist of one sentence answers but there are no graphs or step-by-step guidance.
