difference with geogebra 6
This app is great, especially the export to the tikz and pstricks feature!
I have a question! What is the difference between GeoGebra 5 and GeoGebra 6?
Just don’t use the spreadsheet
I have been using GeoGebra for many years, and I have loved every iteration of it… until now. Most of what it does is still very, very good. It remains my go-to piece of software for dynamic geometry, and I find that I am using the graphing more and more often with my students. However, and this has been true with every iteration of GeoGebra 5 since I upgraded to Yosemite on the Mac, once I try to access the spreadsheet I am not able to put any data into the spreadsheet and I can no longer use the input bar. Once this is fixed, and I have no doubt it will be eventually, I will be back up to five stars.
One other minor thing is that I customize the look of my app so that the buttons are down the left hand side instead of along the top. Yet when I add a spreadsheet or CAS, it wants to put the tools horizontally, but fits them into the side bar making the bar very wide until I go into settings and reclick on the tools on the left button.
Excellent, but minor bugs
Very quick and responsive, and a major tool I use to solve olympiad geometry problems. Features such as circumcircle through three points greatly improve efficiency while drawing diagrams, thus simplifying painfully slow processes that I use when drawing diagrams with ruler and compass. With this software I am able to accurately draw figures from problems, notice true results or conjectures, and quickly determine the necessary steps to arrive at a solution.
However, I notice some mechanical bugs. For instance, Command-W closes not one but all windows. Other than that, the program is great and saves me much hassle in doing geometry problems.
With Family Sharing set up, up to six family members can use this app.
