Algebra View User Interface
By default, the Algebra View is opened next to the Graphics View. In addition, either the Input Bar is displayed at the bottom of the GeoGebra window (GeoGebra Desktop), or an Input Field is integrated directly in the Algebra View (GeoGebra Web and Tablet Apps). The Graphics View Toolbar is displayed at the top of the GeoGebra window, with the Undo / Redo buttons in the top right corner.
Creating Mathematical Objects
In the Algebra View you can directly enter algebraic expressions using the integrated Input Field (GeoGebra Web and Tablet Apps) or the Input Bar at the bottom of the GeoGebra window (GeoGebra Desktop). After hitting the Enter key your algebraic input appears in the Algebra View while its graphical representation is automatically displayed in the Graphics View.
y = 2 x + 3gives you the linear equation in the Algebra View and the corresponding line in the Graphics View.
GeoGebra also offers a wide range of Commands that can be used to create objects in the Algebra View. Just start typing the name of a Command into the Input Bar or Input Field and GeoGebra will offer you a list of Commands that match your input.
Although the Algebra View doesn’t have it’s own Toolbar, you can create Dependent Objects. Select a tool from the Graphics View Toolbar and click on any appropriate object in the Algebra View in order to create a new Dependent Object.
Modifying Mathematical Objects
You can modify the algebraic representation of mathematical objects directly in the Algebra View.
Activate the Move tool and double-click a Free Object in the Algebra View. In the appearing text box you can directly modify its algebraic representation. After hitting the Enter key, both the algebraic representation in the Algebra View and the graphical representation of the object in the Graphics View will automatically adapt to your changes.
Display of Mathematical Objects
By default, mathematical objects are organized by Object Types in the Algebra View. In GeoGebra Desktop, you may use the Style Bar option Sort by in order to re-sort the objects by Dependency, Layer or Construction Order.
The Algebra View Style Bar provides buttons to
- show / hide Auxiliary Objects
- sort the list of objects by different criteria
- display additional Views in the GeoGebra window (GeoGebra Web and Tablet Apps)
Hiding Mathematical Objects in the Algebra View
If you want to hide the algebraic representation of an object in the Algebra View, you may specify the object as an Auxiliary Object. Open the tab Basic of the Properties Dialog and check Auxiliary Object.
By default, Auxiliary Objects are not shown in the Algebra View. You can change this setting by selecting Auxiliary Objects from the Context Menu (right-click or Mac OS Ctrl-click), or by selecting on the appropriate icon in the Algebra View Style Bar.
