I read some of the chapter on the origin of cos and sine. It reads a bit like the telephone book, or possibly a dictionary. Either way, I am going to ignore the copyright, download it to my electric book, and read much of it.
On the contrary, I found the book engaging and interesting. Maor's passion for trigonometry shows through in his clever examples and humorous stories. (Read the prologue about Ahmes the Scribe)
I didn't say I didn't find it interesting. I said it reads like a telephone book. I actually liked that the information seemed to me to be compressed.
