Really exciting news! 1st beta version of our Chrome App have been released!

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:

• lists can be drawn as drop down lists
• Set defaults for Inequalities
• Better axes numbering when grid is on
• Possibility to lock axes ratio
• Zip[ ] supports nested commands
