Geogebra and Marc Renault’s calculus applets

One of my favorite programs is Geogebra.  I discovered it years ago when one of my students was submitting superior graphics in a geometry class in typeset work; I asked her what software she was using and how she found it.  She said “Geogebra.  I just googled ‘free geometry software’.”

Duh.

Geogebra keeps getting better.  Still free.  If you haven’t tried it, you can do so and learn more at http://geogebra.org/cms/.

At the Joint Math Meetings in Boston in January 2012, I met Marc Renault of Shippensburg University.  He was presenting a poster on his work with Geogebra in which he has used the program to create a library of applets for calculus I.  You can find the library at http://webspace.ship.edu/msrenault/GeoGebraCalculus/GeoGebraCalculusApplets.html; I’ve linked to several of these applets in the calculus text I’m writing, taking advantage of the .pdf format to have live links for students to follow.
