This is the tenth and final post in the GeoGebra 4.0 Sneak Peek Series.  In this post, we are going to discuss four more major changes/additions to GeoGebra.

GeoGebra 4.0 Sneak Peek 7: Text box and Command button

The most significant improvement (I think) in GeoGebra 4.0 is the inclusion of Insert text and Insert button tools.  Before, we needed to have knowledge in HTML codes and basic Javascript to create text boxes in applets, but now all we have to do is just use these tools.

GeoGebra 4.0 Sneak Peek 6: The Function Inspector

This is the sixth post in the GeoGebra 4.0 Sneak Peek Series. In this post, we are going to learn about the Function Inspector tool.

GeoGebra 4.0 Sneak Peek: Part I – New Tools

This is the first part of the GeoGebra 4.0 Sneak Peek Series. In this series, we are going to discuss some of the changes in GeoGebra from version 3.2 to 4.0. If you want to have a complete view of the changes, you can read the GeoGebra 4.0 Release Notes.

If you don’t know yet, GeoGebra 4.0 will be released by the end of August this year in a few weeks . If you’re as excited as me and want to try out the new features, you might want to explore the GeoGebra 4.0 Beta release.  This release is, of course, not stable (they may still change some features).

The most evident changes in GeoGebra 4.0 are the new tools. The tools, their icon, and their descriptions are shown below.  Some tools have no icons yet, so I left it blank.  Continue reading
