CSolve in ggb and uploaded of regluar 17 sided polygon
I'm working on a GGbook on regular polygons and the construction of a 17 sided polygon is a well known issue. One can illustrate the solutions in CAS with the command CSolve (COplossen in dutch). In ggb I can create the list of points as solutions of the equation, but it doens't worke once uploaded. https://ggbm.at/mbEuPZ4C
Is there an overflow, a bug, or can I tackle the problem in another way?
Of course I can create directly the polygon with the command polygon, but the point is of course that there's an algebraic solution to.
