Most Helpful Customer Reviews
I was studying for high school algebra 2, and this book only has a few chapters that are in the actual textbook. Trigonometric functions and graphs aren't included, determinants are left out, and Cramer's Rule is poorly explained. There were also about 8 incorrect equations, such as an incorrect ellipse equation. If you want a better book on Algebra II, look at Schaum's Outlines by McGraw Hill. (Check out precalculus or college algebra books.)
Personally, math was never my thing in high school so when I knew I'd be taking math in college I immediately looked for a book like this. Overall it has been very helpful and easy to comprehend. My only negative comment is that it would be better if this book had more practice problems. But, thankfully that is exactly what the "Dummies" books have recently done. They are releasing a Practice Problems book for Algebra 2 at the end of May, which I've already pre-ordered. So together the two books will be the perfect study aids.
It's so well written. In a normal textbook you have to spend time trying to decipher what half the material means and how it relates to the rest of the book, but in this book it's almost as though you are listening to a person explain it to you at a party.
