Geogebra An Open Source Software For Geometry And Algebra
Any object in GeoGebra has dual representation, geometric and algebraic. One can create geometric constructions and objects either interactively in the Graphics View, or by typing the appropriate commands in the input field of the Input bar. The Objects so constructed can be manipulated and explored either interactively in the Graphics View or by changing the parameters in the Algebra View Section. Moving the objects in the Graphics View changes the expressions in the Algebra View accordingly....
