Unfortunately, I haven't found a program yet that does open/closed circles well. I actually do them by hand - just create a tiny circle object, and copy and paste it around. I just save some parent graphs, and then retool them as needed for further examples. You may want to look into GeoGebra to make graphs also. It's free, anyway. If you ever find a good solution to this, please let me know!Dan Wekselgreenehttps://www.blogger.com/profile/08696028020767073620noreply@blogger.comtag:blogger.com,1999:blog-30226356.post-33399310927113335082007-12-06T19:20:00.000-08:002007-12-06T19:20:00.000-08:00Your graphs are done in Sketchpad, no?

The distance between where the students are and what the textbook does is pretty huge, and we'll be looking for a new text at Asilomar this year. Meanwhile - thanks for making these great materials available! I'm nervous about seeing the copy count for this month, though... Have likely gone over the limits of the Math Dept copy budget.<BR/><BR/>Glad you're back and writing again.
