GeoGebra 4.0 Sneak Peek: Part I – New Tools

May 16, 2011 GB GeoGebra

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.

	Attach/Detach Point	Attaches/detaches a point to a particular object.
	Function Inspector	Displays different properties of functions (maximum, minimum, roots, etc). We will discuss this in a separate post.
