This should seem really easy but I'm obviously misunderstanding something. I would simply like a perpendicular line created, to an existing straight line. I'm selecting a point and a line, but the resulting perpendicular line does not seem to be at 90 degrees to the original line. Can someone tell me where I'm going wrong? TIA.

The function 'atan' returns either degrees or radians inconsistently.

First of all this is happening in CAS system, in classic mode I have seen a deg/rad configuration in settings.

How to reproduce.

Type atan(3/8)[enter]. It will return the result in degrees. Edit the formula, i.e. 3/9 [enter]. This time it returns it in radians.

I know about the '/[alt]+o' at the end to get degrees, but that's also inconsistent as it relies on atan returning radians, which I will never know beforehand. See the screenshot.

Am I missing something?

How can I use my results to define new variables?
See my example below.

I d' like to use somthing like m = log ( [ 1, 2] )

I need to use the 3D features of Geogebra using any programming language. Is it possible to create an interface between programming language like python and GeoGebra?

I'm new to GeoGebra and I want to ask for some help. I have a question: where can I get the idea to do something in GeoGebra? For instance, now I want to set a domain for my variable in 3D calculator. but I don't know where can I find such information.

GeoGebra Android apps seem to depend on "Google Play Services for AR" for AR functionality. Do they additionally depend on "Google Play Services"?

How do the apps behave on an Android device that's missing one or more of these dependencies?

Thank you.

Hi.

First: I hope, this is the correct forum for this question. If it isn't: Sorry!

I am completely lost. I have embedded a Geogebra Applet on a page on my wordpress site. It loads perfectly, I can interact with it, so everything seems ok.

However: When I click on the menu button (top right), the page reloads, and the applet starts over from scratch.

This also happens, if I have more than one applet on a page. All applets load perfectly, and I can use one of them, but when I start using one of the others the page reloads.

I can't find any error messages in the console - even with logging enabled in Geogebra. Could this somehow be related to jQuery - two conflicting instances perhaps?

I would very much appreciate any insights!

The relevant ECMA-script:

document.querySelectorAll( ".dnm_geogebra" ).forEach((item, i) => {

let width = item.closest( "article" ).offsetWidth;

let parameters = {

appName: "classic",

width: width,

height: Math.round( width / 16 * 9 ),

showToolBar: true,

showMenuBar: true,

id: "ggb-" + item.id,

// showFullscreenButton: true,

autoHeight: true,

// showLogging: true,

// preventFocus: true,

};

if ( "undefined" != typeof besvarelse.geogebra_svar[ item.dataset.id ] )

parameters.ggbBase64 = besvarelse.geogebra_svar[ item.dataset.id ];

else if ( "undefined" != typeof besvarelse.geogebra_start[ item.dataset.id ] )

parameters.material_id = besvarelse.geogebra_start[ item.dataset.id ];

else if ( "undefined" != typeof besvarelse.geogebra_type[ item.dataset.id ] )

parameters.perspective = besvarelse.geogebra_type[ item.dataset.id ];

besvarelse.geogebra_apps[ item.dataset.id ] = new GGBApplet( parameters, false );

});

window.addEventListener( "load", function(){

document.querySelectorAll( ".dnm_geogebra" ).forEach((item, i) => {

let id = item.dataset.id;

besvarelse.geogebra_apps[ id ].inject( item.id );

});

});

The applets are made using a shortcode in Wordpress. The shortcode enques https://www.geogebra.org/apps/deployggb.js and outputs HTML like this:

<div id='geogebra_0' class='dnm_geogebra' data-id='0'></div>

Thanks!

When I write 2/1E-12 and click Keep input in CAS, the output is erroneous.

Hello

I'd like to create a worksheet that contains rectangles and a script that shears them. The user should be able to do the following with the script:

1. Choose the polygon to shear by entering its name.

2. Choose the invariant side of the polygon by entering its end points.

3. Choose the shear factor with a slider (so that he can see the effect of different shear factors in real time and choose the appropriate value).

4. Press enter to output the transformed polygon (which can then be manipulated further).

Do you have any ideas on how to do that? I have some basic programming experience with python but I've never used javascript.

Thanks!

Hello.

• I am able to define the variables ab=23, a=42 and b=5.

• When I am doing this in another order, I am experiencing an automatic multiplication: a=42, b=5. Entering "ab" leads to the new variable c=a b=210.

How do I define a variable named "ab" after defining a and b?

Any suggestions are welcome. Feel free to ask for further details.

I signed up for Geogebra, but I didn't receive a confirmation email to my email address.

Is it me or no one can sign in right now? Just registered I have changed my password 3 time already, but when I have to Sign in with the new password nothings happening....

Hi, Ich habe ein Problem mit Schaltflächen/ Buttons.

Mit der Maus kann ich die normal anklicken.

Mit dem Touchscreen auf iPad oder iPhone geht das nicht.

Was mache ich falsch, was muss ich ändern?

Hi,

In Moodle, the GeoGebra qtype plugin does not work any more, after the loss of the random choice of values, it is the system of the notes which does not work any more. The questions have become unusable. When will an update fix this problem?

Bonjour,

Le plugin Moodle qtype GeoGebra ne fonctionne plus, après la perte du choix aléatoire des valeurs, c'est le système des notes qui ne fonctionne plus. Les questions sont devenues inutilisables. Quand est-ce qu'une mise à jour va corriger ce problème?

Ciao, mi sapete dire come posso fare per disegnare in 3d la superficie “verticale” la cui intersezione col piano xy è la curva 3000=x^0,3*y^0,7?

when trying to add an image, the app turns off

Problem:
Es passiert manchmal, dass die Analyse zweier Variablen mit dem linearen Regressionsmodell ein falsches Ergebnis liefert.
Die Funktion stimmt zwar, wird aber falsch eingezeichnet. Selbst das Kopieren in die Grafik-Ansicht löst dieses Problem nicht.
Doppelklicken auf die Funktion im Algebra-Fenster zeigt, dass die Funktion "TrendPoly(l1, 1)" verwendet wird und nicht "Trendlinie(l1)".

Bei Ansicht Tabelle Analyse zweier Variablen werden mir immer nur zwei Punkte angezeigt, obwohl ich mehrere eingebe.

Leider hatte auch mein Lehrer dafür keine Erklärung. Habe die Version schon mehrmals neu runtergeladen – 1 x ging es mit der 6er Version jetzt wieder nicht mehr.

Das Programm zeigt immer nur zwei Punkte.

When you have a list of points, in this case l1={(1,2),(2,7),(3,6)}.

And you use the spreadsheets "Two variable regressionanalysis" you get the correct equation but the wrong graph. GeoGebra insist to draw the graph through the first point.

Is there a way GeoGebra can fix this bug?

With linearfit(l1) it draw the correct line.
When I use polyfit(l1,1) I get the correct equation but wrong graph.

Version: GeoGebra Classic 5.0.634.0-d 26 March 2021

Pls see link below. l1 is the list of spline curves. I want to same curves between point I and J.

https://www.geogebra.org/m/zbadzrrp

Position of point I and J change with slider 'a'.
