Currently my Algebra 2 and Trigonometry students use Amsco's textbook.  Years ago I created a notebook for my students to use.  The notes have never been revised, leaving some sections in need of tending to.  I am posting them for anyone to use.  But more importantly, I am posting them as word documents so that interested teachers can download and revise. 

Chapter 10 - More Trigonometric Functions
Chapter 11 - Graphs of Trigonometric Functions
Chapter 15 - Statistics
