The User Interface of the [i]GeoGebra CAS Calculator[/i] consists of the[i] [img]https://wiki.geogebra.org/uploads/thumb/3/36/Av_tab_white48.png/24px-Av_tab_white48.png[/img] Algebra View[/i], the [img]https://wiki.geogebra.org/uploads/9/90/Tools_tab_white24.png[/img] [i]Tools View[/i], the [img]https://wiki.geogebra.org/uploads/c/c0/Table_view_white24.png[/img] [i]Table View [/i]and the [i]Graphics View[/i]. All [i]Views[/i] are dynamically connected, which means that modifications in any [i]View[/i] are immediately displayed in the other [i]View[/i] as well.

Use the [img]https://wiki.geogebra.org/uploads/thumb/3/36/Av_tab_white48.png/24px-Av_tab_white48.png[/img] [i]Algebra View [/i]button in order to open the[i] Algebra View. [/i]Enter algebraic input, commands and functions into the [i]Input bar [/i]by using the keyboard. The graphical representation of these objects is displayed in the [i]Graphics View[/i]. The algebraic numeric representation of all created objects is shown in the [img]https://wiki.geogebra.org/uploads/thumb/3/36/Av_tab_white48.png/24px-Av_tab_white48.png[/img][i] Algebra View [/i]as well.

Use the [img]https://wiki.geogebra.org/uploads/9/90/Tools_tab_white24.png[/img] [i]Tools View [/i]button in order to open the [i]Tools View [/i]providing access to the categories of [i]GeoGebra t[/i]ools. Select any tool and create new objects in the [i]Graphics View[/i]. [br][br]Note: The [img]https://wiki.geogebra.org/uploads/9/90/Tools_tab_white24.png[/img] [i]Tools View [/i]shows a selection of most important tools. If you want to see more tools, select [i]MORE[/i] at the end of the [img]https://wiki.geogebra.org/uploads/9/90/Tools_tab_white24.png[/img] [i]Tools View[/i].

Use the [img]https://wiki.geogebra.org/uploads/c/c0/Table_view_white24.png[/img] [i]Table View [/i]button in order to open the [i]Table View. [/i]If you have activated the table of values for a function, you can find a table of values in a specified range there.

If you prefer to work only with the [i]Graphics View[/i] and not the [img]https://wiki.geogebra.org/uploads/thumb/3/36/Av_tab_white48.png/24px-Av_tab_white48.png[/img] [i]Algebra View[/i], the[i] [img]https://wiki.geogebra.org/uploads/9/90/Tools_tab_white24.png[/img] Tools View [/i]or the [img]https://wiki.geogebra.org/uploads/c/c0/Table_view_white24.png[/img] [i]Table View, [/i]you may hide these [i]Views [/i]by clicking on [img width=20,height=21]https://lh5.googleusercontent.com/2fTJsdl9ZrSv9ekWcYnOd4HCZxRdNFBLqZnikfVd9EwOWLgy6KIxuuW3K1PNPOif8GrQBrQRlLYGQDOpcCG-DJn5NzemzVxHzXpAHw3D3pubn31RH9-adBgYiq7VMKTcDlSHt4Ku[/img].[br]You may display them again at any time using [img width=20,height=22]https://lh3.googleusercontent.com/n8FIFKF6_7Q1sg2YjeMZJC2tR6oVvu_pRzXRb-A2H-e8--EshDwo76_MsDF6BXC7HKkqJgcKhnBm-FtSg2fEYhu8gGwDryf45MjtT0teNEJW79Hcj2oaSj5S_o4iIzo2iqDkoqcy[/img].

Select [img]https://wiki.geogebra.org/uploads/thumb/d/d2/Ic_settings_black.svg/16px-Ic_settings_black.svg.png[/img] [i]Settings [/i]in the upper right corner to open the [i]Settings[/i]. Decide whether you want to show the axes, a coordinate grid or to change the view on the objects. You may also open further settings to change the general settings (e.g.: rounding, language), the [i]Graphics View[/i] settings (e.g.: grid type, distances on the axes) as well as the [i]Algebra View[/i] settings (e.g.: descriptions).

The [i]GeoGebra CAS Calculator[/i] combines all features of the [i]GeoGebra Graphing Calculator[/i] with symbolic computations and CAS specific commands.[br]In the next activites of this tutorial you will learn how to put in CAS commands and symbolic computations like the integral or derivative.[br][br]If you are new to GeoGebra, you might want to check out our [url=https://www.geogebra.org/m/vd6UC685]GeoGebra Graphing Calculator tutorial[/url] first.
