Some GeoGebra examples

25 September , 2009

Just thought I should share some good examples of visual mathematics with you.

The first one comes from David Richeson, and pictures what happens when the rays striking a parabola do not come at a straight angle to the vertix.

The second one is from the excellent blog Lessons taught, lessons learnt. It shows some of the statistical capabilities of the new version of GeoGebra.
