Graphing Perspective

The [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Graphing Perspective[/i] includes the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Algebra View[/i] and the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i]. By default, the [img]https://wiki.geogebra.org/uploads/thumb/7/7d/Stylingbar_graphicsview_show_or_hide_the_axes.svg/16px-Stylingbar_graphicsview_show_or_hide_the_axes.svg.png[/img] [i]coordinate axes[/i] are shown and the [i]Graphics View Toolbar[/i] is displayed at the top of the [i]GeoGebra Classic [/i]app[size=100], with the [img]https://wiki.geogebra.org/uploads/thumb/3/38/Menu-edit-undo.svg/16px-Menu-edit-undo.svg.png[/img] [size=100][size=100][img]https://wiki.geogebra.org/uploads/thumb/8/85/Menu-edit-redo.svg/16px-Menu-edit-redo.svg.png[/img][/size][/size] [i]Undo / Redo[/i] buttons in the top right corner.[/size]
The Algebra View
In the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Algebra View[/i] you can directly enter algebraic expressions using the [i]Input Bar[/i]. After hitting the [i]Enter [/i]key your algebraic input appears in the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Algebra View.[br][br][/i][b]Note:[/b] At the same time, the corresponding graphical representation is automatically displayed in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i].[br][br][b]Example:[/b] The input [math]y=2x+3[/math] gives you the linear equation in the [img]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i]Algebra View[/i] and the corresponding line in the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i].

[br][br][b]Note:[/b] At the same time, their algebraic representations are dynamically updated in the [img width=16,height=16]https://wiki.geogebra.org/uploads/thumb/4/40/Menu_view_algebra.svg/16px-Menu_view_algebra.svg.png[/img] [i][url=https://www.geogebra.org/m/XUv5mXTm#material/ncjbw5zr]Algebra View[/url][/i].[br][br][br][br][b]Copy & Paste[/b][br]Via Keybord Shortcut Ctrl + C and Ctrl + V (Mac OS:Ctrl + C and Ctrl + V) you can [i]Copy and Paste[/i] selected objects (except if they depend on the coordinate axes) into either the same or into another window. [br][br][b]Note:[/b] [i]Copy and Paste[/i] will copy every ancestor of the selected objects but makes the non-selected objects invisible.[br][b]Example:[/b] If you copy objects depending on sliders into a new window, it will copy the slider (invisible) into the window, too.[br][br]The pasted object is fixed when you click on the [img width=16,height=16]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i]. If the copied object depends on at least one point then it can snap onto existing points when pasted (but only the point following the mouse pointer will do this).

Animating a construction

[i]GeoGebra [/i]offers the possibility to animate sliders (numbers, angles) and points on paths (segment, line, function, curve, etc.). While an animation is running, [i]GeoGebra [/i]remains fully functional. This allows you to make changes to your construction while the animation is playing.
Instructions
[table][tr][td]1.[br][/td][td][/td][td]Right-click (MacOS: [i]Ctrl-click[/i]) on the blue slider[i][/i] and choose [i]Animation[/i] from the appearing context menu.[br][b]Hint:[/b] An [i]Animation[/i] button appears in the lower left corner of the [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i].

Animation settings

After reaching the maximum value of the slider, it jumps back to the minimum value and continues the animation.[br]⇐ Decreasing[br]The slider value is always decreasing. After reaching the minimum value of the slider, it jumps back to the maximum value and continues the animation.[br]⇒ Increasing (Once)[br]The slider value is increasing. After reaching the maximum value of the slider, the animation stops.
