Query: Don't buy this book.

I was looking for a book with Math and Physics formulas and explenation how to use them in game programming. I saw this book and took a glance in it in the book store and it looked verry nice.But it have been a big disappointment. The first two thirds of it is either verry simple (points and lines) or "strange" stuff like 3D rotation. If you are intrested in 3D game programming you proberbly don't buy a book for beginners. Also the structure of the book is verry wothless, it takes time to find what you are looking for.I wold not recomend this if you are choosing between this book and another. I'll give it 2 two stars, and thats a high grade for it.
