GeoGebra on the Web

Really exciting news. We have released the first beta version of our Chrome App:

GeoGebra 4.2 News

CAS:

Some commands work in CAS now: Length[point], Join, Append, Line (not appearing in autocomplete yet)
eg SolveODE[y=-y]

New commands:

AttachCopyToView[Object,<View 0|1|2>]
ContinuedFraction[ <Number>, <Level - optional>, <Shorthand true|false> ]
Invert[Function] -- works for functions with one occurence of x.
InverseLogNormal[ ]
InverseLogistic[ ]
SolveODE[f'(x,y)] -- result controlable by sliders (open auxiliary objects and make them visible first)
SolveODE[f'(x,y),Point] -- draws integral line through point
ScientificText[ ]
SlopeField[ ] eg SlopeField[-x/(y+0.1x)]
Integral[-x/(y+0.1x), A]
Numerator[ ] / Denominator[ ] now work for functions of more than one variable
AreConcyclic[ ]
AreColinear[ ]

Other improvements:

Some nice resources on GeoGebra:

And from other sites:

It would be great if you could join us at CADGME on 22-24 June 2012 and CAME on 21 June 2012 both held in Novi Sad, Serbia.
Follow the Mascheroni CAD Team: GeoGebra Italia Blog One of their latest project( "A lesson with GeoGebra".) has been awarded at I Giovani e le Scienze 2012!
Sign up for the Midwest GeoGebra Journal. They are currently recruiting volunteers to review manuscripts for the journal for publication in 2012 and looking for funding so that the GeoGebra Midwest Conference can be free for participants.
The FMSP is running an online Geogebra for A level Maths course, More info
GeoGebra Ambassador Lakshmi
Masters degree and Doctorate degree in Mathematic Education in Chile (Spanish)
