too technical, and talk about details before the big picture (if any)
I downloaded their sample chapter on their website, for "A brief tutorial". I am a very technical person -- even so, I find the book too technical.
It talks about the details and fine details, before you know what the big picture is, or what is going on, very much like some textbooks I had back in Asia.
It will be much better if it gives a simple and useful solution to an issue, and then explain the different parts and give big pictures and go top down.
You can try and download that chapter to read it. An example of what I feel is:
Sine and cosine are very simple math functions. But you can explain it so that people don't know what's going on:
1) the simple and easy to understand version: sine gives you a ratio of the length of opposite side of that angle to the hypotenuse of the triangle, for a right angle triangle, so that when we know the angle, then we know the ratio, and if we know one side's length, we can find out the length of the other side. Simple enough?
2) the complex version: sine is a function whereby mapping of an angle, sometimes degree, sometimes radian, is transformed to a number between 0 and 1, inclusive. Coupled with cosine, you have properties of sine squared theta plus cosine squared theta equals one, and all kinds of interested properties. And the smart students will already know there is also tangent, which is not bound between 0 and 1. These are very useful in calculus, and it is a much advanced topic and you will know about it in university or in some cases, in high school. Ok, that's for today, and remember to go home and do your homework.
