In order to delete the stroke you previously created, erase it totally in the Graphics View, or use the Context Menu of the object, or just delete the corresponding item in Algebra View. To erase a portion of your notes created in the Graphics View with the Pen Tool, press and hold the right mouse button while moving it on the notes you want to delete. The default colour of the pen is black, but you can change the pen properties (colour, style, and thickness) using the Styling Bar. Therefore you can use several operations on them (e.g. GeoGebra stores the notes you traced in the Graphic View as a PenStroke (assigning the name stroke to it). GeoGebra Classic 5: A slightly older version of GeoGebra that comes with all the calculator tools and spreadsheet and probability tools. To add a freehand note onto a region of the Graphics View, activate the tool and draw on your touch screen or with your mouse by holding the left mouse button This makes the Pen Tool particularly useful when using GeoGebra for presentations or with multimedia interactive whiteboards. You may directly click on the little Show / Hide Object icon in order to change the visibility status of the object in the Graphics View.The Pen Tool allows the user to add freehand notes and drawings to the Graphics View. In the CAS View, the icon to the left of every row shows the current visibility state (shown or hidden) of the object defined in it (when possible). display additional Views in the GeoGebra window (GeoGebra Web and Tablet Apps).display a virtual keyboard (GeoGebra Desktop).change the text style ( bold and italics) and color.The CAS View Style Bar provides buttons to Copy as Image: Copies the cell contents in PNG format to your computer’s clipboard, so it can be pasted into an Image object or in a word processing document.ĭisplay of Mathematical Objects CAS View Style Bar.Copy as LibreOffice Formula: Copies the cell contents in LibreOffice formula format to your computer’s clipboard, so it can be pasted in a word processing document.Copy as LaTeX: Copies the cell contents in LaTeX format to the your computer’s clipboard, so it can be pasted into a Text object or a LaTeX editor. Explore our iconic Museum Classic collection, contemporary timepieces and.Then, right click on a new cell in order to show the Paste option. Copy: Copies the cell contents to the your computer’s clipboard.In the GeoGebra Desktop Version you can right click (MacOS: Ctrl-click) on a CAS output cell in order to show a Context Menu with the following options: Note: To copy the contents of more than one CAS row as LaTeX, select the rows you want with Ctrl-click (MacOS: Cmd-click), then right-click (MacOS: Ctrl-click) on the row header and select Copy as LaTeX. In the CAS View of GeoGebra´s Desktop Version the following keyboard shortcuts help you to evaluate or check your input. While in the Input Bar you can use both a(b+c) and a*(b+c) for multiplication, in the CAS View only a*(b+c) is valid. Multiplication needs to be marked explicitly.See the section about assignments for details. This means that the input a=2 will not assign value 2 to a. You may suppress any output with a semicolon at the end of your input, e.g. ![]() Note: Instead of using these keyboard shortcuts, you may also use the corresponding Tools of the CAS View Toolbar. = is used for equations and := for assignments. In the CAS View of GeoGebras Desktop Version the following keyboard shortcuts help you to evaluate or check your input.You can use variables that were not assigned any value.You can use these Input Fields in the same way as the normal Input Bar, with the following differences: It consists of cells with an Input Field at the top and output display at the bottom. ![]() The CAS View allows you to use GeoGebra's CAS (Computer Algebra System) for symbolic computations. The CAS View is part of the CAS Perspective, although you may change the layout of GeoGebra's user interface according to your needs.Ĭreating Mathematical Objects Direct Input GeoGebra Classic 6 (various free tools for geometry, spreadsheet, probability and CAS) The following tools are available only for Android and iOS devices: 3D Graphing (3D functions, plot surfaces and 3D geometry) Augmented Reality (3D math with Augmented Reality) Note: All online GeoGebra Apps can be found here.
