Comment t racer une courbe dont on connaît un système d'équations paramétriques ?
Par exemple, une hélice
x = r cos(at)
y = r sin (at)
z = by
Merci !

In Input bar, enter:
GeoGebra will create the sliders for r, a, b with default values. Adjust the parameters settings (e.g. r>0, etc..).
Please remember to insert a blank space or a product symbol * between e.g. a and t so they are recognized as different variables and parameters.
Open 3D View to see it.
See also this wiki page: https://wiki.geogebra.org/f... for further informations and options.
P.S. I suppose that for the expression for z you meant b t (instead of b y)
