One post for the five-pointed star

Having made 6- and 8-pointed stars, the next step was to make 3- to 7-pointed stars.
I eventually found the required proportions after more experimenting in Geogebra. For a short edge of 1 unit, the long edge needs to be 3.73, 2.41, 2.0, 1.73 and 1.6 for 3- to 7-points.
Odd numbers of units are awkward for choosing colours: either every unit a different colour or use 2 or 3 colours.
As the number of units goes up and beyond 10, the folded locking flap becomes tiny and almost useless.

Eight-pointed star folded from eight 3:2 rectangles.
A similar folding method as before, but I had to model the unit in Geogebra to find that the required proportion was 3:2.

Hat jemand hier schon mal per #STACK + #JSXGraph oder #Geogebra, eine Aufgabe erstellt für #Moodle Tests, in der man graphisch eine Vektoraddition bzw. Kräfteaddition konstruieren musste per Parallelogramm?
Ich würde gerne sehen, wie das angegangen wurde, weil ich gerne ausreizen würde was möglich ist mit STACK+ Grafik.
Question à la #teamprof #maths : Je voudrais résoudre une équation différentielle avec #geogebra.
Je dispose:
- de l'équation
- d'une fonction qui est solution particulière
- d'un point de cette fonction.
Manuellement, ça ne pose aucun souci. Avec Géogebra, je ne sais pas comment utiliser ResolEquaDiff.
-> Edit: en fait, pas besoin d'entrer la fonction particulière.
