This book is at the perfect level for someone who is good, but not great, at math. It's good for someone who wants to use a technique to solve a physics problems without having to sift through incomprehensible math jargon, notation, and esoteric proofs.<br><br>The strengths of the book are (i) it covers pretty much everything you will use in a typical physics course and (ii) it is written in more accessible language and notation.<br><br>The weaknesses of the book are (i) it skips some proofs and higher-level techniques and (ii) the explanations may be longer than necessary, if you just want a reference.<br><br>As a physics professor, I typically check this book first when I'm a rusty on a point (or have a research student that is learning something new). Then, I move on to more advanced books or journal articles if I need more detail.
