Common questions about GeoGebra Apps
Why are there so many different apps?
[size=100]In order to satisfy our user community while simultaneously being compliant with regulations for high-stakes testing, we have different [i]GeoGebra[/i] apps from which you can choose. This allows students to use the power of our apps for high-stakes tests and paper exams while restricting their access to the internet or other software that are not allowed during these tests. At any time, you can also use the [i]Calculator Suite[/i] or [i]Classic[/i] app to access the fullest power of [i]GeoGebra. [br][/i][br]Have a look at the [url=https://www.geogebra.org/m/shfwqcpr]Comparison of GeoGebra Math Apps[/url] to find the right app that meets the testing requirements of your school district, state, or ministry of education. [/size]
How can I send a message to an author?

Why are the CAS commands not working in Graphing Calculator?
We have removed all CAS commands and geometric construction features from our [i]Graphing Calculator[/i], as many states and countries do not allow students to access these features on high-stakes exams. You can still use numeric versions of these commands. [br][br]Symbolic computations like the integral are now gathered in our [i]CAS Calculator[/i] app which is available for Android on the [url=https://play.google.com/store/apps/details?id=org.geogebra.android.cascalc]Google Play Store[/url] and for iOS on the [url=https://itunes.apple.com/us/app/geogebra-cas-calculator/id1436278267?mt=8]App Store[/url]. You can also use our [i]Calculator Suite [/i]app for symbolic computations. The [i]Suite Calculator[/i] is also available for Android on [url=https://play.google.com/store/apps/details?id=org.geogebra.android.calculator.suite]Google Play Store[/url] and for iOS on the [url=https://apps.apple.com/us/app/geogebra-calculator-suite/id1504416652]App Store[/url].
Which commands can I use in the CAS app?

You can check here if your Android phone or tablet supports AR: [url=https://developers.google.com/ar/discover/supported-devices]https://developers.google.com/ar/discover/supported-devices[/url][br]For Android devices, you will also need to install Google Play Services for AR: [url=https://play.google.com/store/apps/details?id=com.google.ar.core&hl=en]https://play.google.com/store/apps/details?id=com.google.ar.core&hl=en[/url][br]
Why are undefined points not shown when plotting a graph?
Invalid values are not excluded, because [i]GeoGebra[/i] uses the [url=https://en.m.wikipedia.org/wiki/Extended_real_number_line]extended real number line[/url]. So this is the expected behavior. [br]
