Algebra View
The algebraic representations of all created objects (i.e. coordinates, equations) are listed in the
Algebra View in the order of their creation.
You can enter algebraic input or commands into the Input Bar in
Algebra View.
For entering algebraic expressions you can use the built-in
Virtual Keyboard, which contains four different layouts for
Virtual Keyboard. You can close the
Virtual Keyboard at any time by clicking anywhere in the 3D Graphics View. If you're using the 3D Calculator on a desktop PC you can also use your external keyboard.
The provided equation editor makes it very easy to enter complex mathematical expressions without losing track of what you are typing.
A built-in help for using commands can be found in every app. To get an overview of all commands in the online App, select the
Input help button and choose Help. On mobile devices select the
More button on the upper right corner of the
Virtual Keyboard.
Using the online App, you can also just start typing a command. After three letters the app will suggest available commands including their parameters.
Note: Commands can also be entered in lower case and will be automatically changed to upper case after pressing enter.

Additional options
Edit existing objects
Select an existing object in the
Algebra View to enable editing.
Input Help
The
Input Help button left of the Input Bar allows you to select the type of input and get help. You can select
Help to open the Input Help screen, where all commands and mathematical functions are listed.
Show / Hide Objects
Use the
Visibility button left of an object in the
Algebra View to hide it in the 3D Graphics View (e.g. auxiliary objects). To show a hidden object again, click on the disabled
Visibility button in the
Algebra View.
Delete Objects
You can delete any object by selecting the
More button next to its algebraic representation in the
Algebra View and selecting
Delete.

Extend the Algebra View
If you don't need the Graphics View you can extend the
Algebra View to full screen so you have more space for your input and explorations.
