Hello! Thanks for visiting my Precalculus page. Alas, you are too early - I have not begun to work on this. Meanwhile, here is a fun site for you on fractiles: http://illuminations.nctm.org/activitydetail.aspx?id=17
Here is a Precalc tutorial site. I am going to collect some of these and review them when I get time. Stay tuned!
