Review title: Short, but difficult
Product review: Good: This is not a refresher, it is an undergraduate level textbook without the fluff. You will contemplate the meaning of mathematics and ask yourself "what" a lot (As intended and stated in the preface). The paragraphs often read like riddles, but the math is accurately stated (if you have unlimited time to understand what the author is trying to get across). The few figures that seemed pertaining will carry you somewhat.Bad: Sample problems are too few and not illustrative or instructive. Most problems at the end of the chapter do not have full solutions. Why not? Was the author hoping to sell a student solution manual? The author skips ratio, proportion, and phase in periodic functions.
