- for spreadsheet, i followed your advice and selected "insert>session giac" then it seems to work, but if i type spreadsheet("name_of_file") i dont know what sort of fil i must give, i suppose that no excel nor Ooo fil can match, so what ? how to create a simple sreadsheet with 6x4 cells for example... Where to find a help on this topic ?in the same way, how can i find a manual fin order to know how the function geo2d works ?Just type any filename you wish to save your spreadsheet.
If it does not exist it will be created, if it exists it will be loaded.
I usually use .tab as extension, e.g. "tableur.tab".
Do not use an existing OO or Excel file, it won't work. But you can copy/paste
from OO, and also import CSV file once the spreadsheet is opened
in a new windows.
The same applies for geo2d and 3d (no import/export here).
The documentation of Xcas applies for what you can do in
the spreadsheet or interactive geometry.
