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
