**The below EMT 668 writeups represent just some of the
investigations done in this course. The investigations have been facilitated
by the software packages of Geometer's
Sketchpad, Algebra Xpresser, Excel, Theorists, Graphing Calculator and Xfunction.**

**Some of the writeups will have links to Geometer's Sketchpad
which will allow you to see it all first hand. If you have sketchpad on
your computer and you would like to set your browser up so that you can
investigate on your own, click here.
For those of you who don't own sketchpad, I will also provide a Java version
of the investigation so that you don't miss out either (under construction).**
