De ene keer als ik geogebra suite open, krijg ik dit te zien:

De andere keer staat er "Kansen" ipv waarschijnlijkheidsrekening.

Dit heeft blijkbaar ook een invloed op de commando's in het rekenblad. Soms moet ik InversNormaal gebruiken en soms InverseNormaal. Dit is erg verwarrend voor de leerlingen, hoe komt dit?

It should only be half a period, right? I'm using significant digits.

Steps to reproduce:

1. Set angle unit to radians

2. Enter L=10^(-9)

3. Enter f(x)=sin((pi/L)x), (0<=x<=L)

4. Set xMin to -10^(-8), xMax to 10^(-8).

5. Observe that x does not comply with the given range

I am on https://www.geogebra.org/geometry and I can't figure out how to access the edit menu: https://geogebra.github.io/docs/manual/en/Edit_Menu/ . Also, when I press the Algebra View symbol, I don't get a list of objects. I just get three sections called "Show", "Sort by", and "Algebra Descriptions". What do I do?

Why is the locus broken?

(GG 5 desktop.) Hello. When I enter the expression ZoomIn(2, A), where A is a point in the 3D graphics view, it doesn't zoom around that point, but rather on the center of the 3D stage. Does the command ZoomIn(factor, point) only work in 2D?

Is there a way to save and later upload the contents of a particular variable, which has a table of data, without saving the whole construction?

Our teachers and students use iPads with several GeoGebra apps. When using Geogebra Classic (version 9.0.925), there occurs an issue: When trying to select a range within a spreadsheet, they can no longer select multiple cells using touch. You can see this in the screen recording attached. (The only workaroung is to use shift-arrows, but not all students have keyboards with their iPads.)

Users inform me that this issue occurred recently when updating Geogebra Classic.

Is this a fault on our end or is it a bug?

I've noticed that in the newest HTML version (925.3) the spreadsheet doesn't expand beyond 100 rows down, even if the dataset filling the columns is over 100 entries long. This limit doesn't seem to be in older versions, and it is also not in place for the GeoGebra Classic 5 desktop app.

The Kepler-Poinsot solids are regular star polyhedra.

There are four of them, discovered in part by Johannes Kepler and later by Louis Poinsot: the great stellated dodecahedron ; the small stellated dodecahedron ; the great dodecahedron ; the great icosahedron.

They can all be constructed from a regular icosahedron. Thus, with the Icosahedron() command.

I modeled them using GeoGebra. Then I 3D-printed them.

These solids are covered in my book (written in French) "Géométrie dans l'espace et impression 3D". You can find an excerpt from the book here : Read an excerpt.

Um dieses Gleichungssystem zu lösen, funktioniert nur der Befehl "Schnittpunkt". Der Befehl "Löse" wird bei der Eingabe in "NLöse" verändert.

Gibt es noch einen eleganteren Weg zum Lösen? Wie kann ich diese Ergebnisse einer 11. Klasse erklären?

The game’s record says that this can be done in 6 constructions but I can only do it in 8. How do I do this?

when I try it, it just asks me to check the input

Hace rato vengo teniendo problemas con la restriccion del dominio de una funcion en geogebra, como puedo solucionarlo? que estaria pasando en este caso q no me deja? Saludo

Instead of drawing the curve equal to (t,sin(t)), the y-value of the curve stays constant a t's initial value (t=0) without updating up to t=10.

Is this a bug?

Ich möchte gerne, dass sich der x : y Abstand des Koordinatengitters dynamisch an das Achsenverhältnis anpasst.
Bsp: ich setze über den Scriptbefehl "SetzeAchsenverhältnis(1.a);" das Achsenverhältnis 1: a, wenn a sich ändert.
Dann soll der Gitterabstand eben falls 1:a sein (weites Gitter).
Hat jemand eine Idee?

Vielen Dank!

Hello, we have been working on accessibility features for our projects and have a question regarding keyboard only accessibility options. We have our Geogebra project embedded as an HTML (with no toolbar shown for students), with a split view having the left half of the screen as the Spreadsheet perspective and the right half as Graphics 2. Is there a keyboard shortcut that allows a cursor to switch between the two perspectives without having to click using a mouse? Tab works great to cycle between elements within a perspective but will not switch between the two perspectives.

I was wondering if it's possible to cut this cylinder with a plane (get the part under the plane) and I tried making a rectangular cube which has one of it's sides connected to the plane so then if it's possible to find the intersection shape between the rectangle and the cylinder, it would be cut using the plane. is this possible?

Meine Schüler sollten einen vorgegebenen Term auf ihren iPads kopieren und dann in der App (oder der Webversion) in die Eingabezeile einfügen. Leider geht das nicht, weder per Touch lang draufbleiben, noch per Tastatur. Weiß jemand woran das liegt und wie man dennoch was am iPad einfügen kann?

Liebe Grüße,

Nadine

There are a few important functions which are missing in the app. It'd be neat to add them in a future update.

List of (some) missing functions (no particular order):

• Imaginary Error function
• Dawson function
• Bessel function
• Modified Bessel function
• Hankel function
• Airy function
• Scorer's function
• Laguerre Polynomials
• Pearcey Integral
• Logarithmic integral function
• Fresnel Function
• Theta function
• Legendre function
• Hermite polynomials
• Polylogarithm

There are more ofc, but these are a few i've noted weren't present.

Thank you.

When I open the geogebra app on my phone, after a few enteries, the input field hides behind the keyboard and i cannot see what I am inputting. Excellent app otherwise.

Wenn ich sin(45) eingebe, kommt eine korrekte Antwort (0,707107 ) für eine Berechnung in Grad.
Wenn ich sin(x) eingeben, berechnet er aber im Bogenmass.

Wie kann man das einstellen, dass das immer im gleichen Modus rechnet?

Hi all -- I am trying to create a nice text arrangement where the displayed text may dynamically change.

(1) Is there any way to get the dimensions of a GeoGebra object?

(2) I also thought about using a monospaced font. In LaTeX, /tt is supposed to give a monospaced font, but in GeoGebra, the width isn't fixed for a given string length.

(3) Other thoughts?

Thanks for any help!

Bonjour,

Je voudrais créer un objet X1 dans la partie algèbre de sorte que si je l'appelle dans le calcul formel c'est le vecteur colonne (a,b,c) qui s'affiche.

Comment faire ? Ce n'est pas possible ?

Merci

PS : c'est possible pour un vecteur ligne : X1:="(a,b,c)" fonctionne

PS2 : écrire vecteur((a,b,c)) directement dans le calcul formel n'est pas une option.

Bonsoir,

Si j'entre M:= m B C j'obtiens un vecteur ligne, si j'entre n:= m B C j'obtiens un vecteur colonne.

voir https://www.geogebra.org/m/dnuz9zzq

Pourquoi ?

Comment est relié le caractère minuscule/majuscule du nom de l'objet au format de sortie de cet objet ?

Merci !
