Some GeoGebra examples

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.

  1. I click the link for striking a parabola do not come at a straight angle and I could see the aplet. I don’t know why.
