12.1 Getting Started

On and Off

This web edition of the textbook does not embed the calculator in the page. To follow along with the examples in this appendix, open the free GeoGebra Graphing Calculator at www.geogebra.org/graphing in a separate browser tab or window, or install the GeoGebra Graphing Calculator app on a phone or tablet. If your screen is wide enough, arrange the calculator and the book side by side. When you are finished, simply close the calculator tab or app.

Numbers and Operations

We press to tell the calculator to store the computation. We can use the scroll bar to see the input box or the output history of previous computations.

The calculator has a key for the value of $\pi$.

Delete and Undo

Press the backspace key (shown in the keyboard image) to delete the character before the cursor or any highlighted characters.

To remove an item from the output history, tap the kebab menu icon (three vertically stacked dots) to the right of the item, then tap "Delete".

To remove the most recent item in the output history, tap the Undo icon in the Graphics View. (The icon looks like an arched arrow pointing left.)
