There are full images in this. This book is much larger than what is typically available for free. The images look good, but they are typically roughly two times too large at the moment. Also, all places where TeX is used, a too-large blocky image is used instead. For example, "(3,3)" is presented three times larger than the surrounding text. There are many of these on every page. In this particular ebook, it's inconsistently sized. For example, see location 4561-71.
Not all images seem to have made it. For example, on location 4513-28, three images are listed as "not available". Since this is a digital textbook, I'm sure those will be fixed. The errors above will also probably be addressed quickly.
Despite the above mentioned (and perhaps soon-fixed) flaws, this is worthwhile download.
The book layout isn't that great. The Kindle formatting isn't that great either. For example, the Table of Contents is located at the end of the book, so if you start at the beginning of the book, you're a little confused as to the aims for the first chapter.
So why 5 stars? If you're a student, this book is worth downloading. If I was retaking a University math course, I'd download it to have as a second reference source. And it's free.
The book was clear and easy to understand. The style and language reflected the target audience - I quickly got back into the high-school-math-book mode though with a few things have changed in the last xx years since I was in school- up to date references/examples, URLs given in a few spots (high school for me was pre-Internet), many sections on using graphing calculators, etc.
For the most part I have no issues with the content or the way it was presented. I was a little taken aback the first time I came upon a section on using a graphing calculator but I guess you teach the kids what they'll be using. No, it wasn't that: my main problem is with the Kindle implementation.
The problem is that most of the equations are images. OK, most of the images are fine. In fact, pretty good. It's just that it seems they tried to fit multiple lines worth of equations onto 1 line and it often came out unreadable.
The first thing I did was turn my Kindle sideways. This helped but I was still missing quite a bit. I then tried the PC version. Even better yet I was still missing a lot.
In a few places I was missing main parts of the content, in which case I just found it on line. Trig is trig. More often how the concept was derived was unreadable. I could work it out on my own without a problem: I mean this is high school math and not rocket science.Read more ›

Although I have a college textbook explaining trigonometry, this is a really great alternative for it. Read morePublished 13 months ago by Osvaldo
Trig SUCKS. But this is the way to try to understand that it can be comprehended and does a pretty good job of it. It's a good thing I don't get tested.Published 15 months ago by John Rommel
May be a good textbook, but doesn't work as a KINDLE version because all the mathematical formulas and diagrams are fixed at a much too small size to read.Published 19 months ago by SJ
