* Printing Suggestions for
Typed Files*

I
recommend two-page-to-a-side and/or double-sided printing to save paper. If the
typed print is too small, try something like Page Setup: Scale: 110% or 105%,
unless print gets cut off (100% may be better for handwritten notes). Color
printing is nice, but B&W printing is cheaper.

These are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is
compatible with your system!

** WEBSITE COMMENTS:**** **Link
to these web pages, not individual pdf files! I am
always revising these notes; I need to revise the page references after Chapter
1. These course notes are currently keyed to Larson's *Precalculus*, but
they can stand alone, and they will be formed into an independent book
(complete with exercises) later. The revolutionary "Frame Method" for
graphing trig functions was inspired by Tom Teegarden
and Karl Smith's *Trigonometry* text. Suggestions are welcome! - Thanks
