Hi, I am creating an activity to illustrate various rotations around different axes. My goal is to enhance the display by showing the axes (one portion as a dashed line and the other as a vector) and to insert the texts (Ox, Oy, Oz) in an optimal manner. Any ideas to optimize the rendering? Thank you.

Hi,

I want to illustrate the intersection between The ellipsoid   "x^2/4 + y^2/9 + z^2/16 = 1"and the plane  "z = 3"

Normally, I should obtain an ellipse G1, but its graph does not match the graph obtained ? Thanks for your ideas

Hi, I'm trying to add the display of graphs G1, G2, and G3 (representing the intersections -AnimCompl file-) to my three animations (G5Ex2-file). I've tried using the background option and the display command, but without success. Thank you for your help.

Hi,

I don't understand why my ruled surface is not displayed with this code in my animation. Maybe there is an issue with an option? All my previous animations were displayed normally. Any ideas? Thank you
