This book was seriously lacking.
It would not explain why one did anything, and just show a proof. Then it would only use the most trivial example to show how to do something, sometimes using the same equation over and over again for different methods of solving problems. Sometimes the examples would skip steps making them hard to follow. Then it would constantly refer back to things in earlier chapters rather than talk about them again. Given that this book costs $150, I think they could have afforded to use a few more pages to explain why they where even do what they where doing, and to not have been so lazy with their examples.
To compound this situation, the teacher I had lacked the ability to teach anything, so I had to learn everything on my own. So having a book that was at least useful would have been a help.
