Free Precalculus Textbook Download - Stitz-Zeager.com

[Ivan92]

Hey guys. I just wanted to share this with you all. I was looking for a free Precalculus textbook (or something close to it) all over the net. I could not find any until I stumbled upon this site:

http://www.stitz-zeager.com/

He has a free College Algebra, College Trigonometry, and a PreCalculus textbook as a free download. Took a skim through the PreCalculus book and it seems legit. Though if you want print, you are going to have to pay a fee. I did not see this anywhere on the forums so that is why I am sharing it with you all. I just thought if anyone was looking for anything like this, I would save them the search. :)
