Michael Corral has released another open source mathematics textbook, this one being a very nice (elementary) treatment of trigonometry. http://mecmath.net/trig/
He mentions Sage in the preface, and late in the book says: There is a lot of mathematical software available, both commercial and noncommercial. One of the best is Sage, a powerful and free open- source mathematics software system which can be run on your own computer or through a web interface. It is based on Python and can do both numerical and symbolic computation, as well as graphing and much more. Visit http://www.sagemath.org for more details. No Sage code in the book, but a nice plug all the same.
