With students all cells will be "live" and may be changed at any time. So any change in the sheet means to compute again (almost) all cells below.
Theses sheets are comparable to excel-sheets. An opposite point of view (that I prefer and easiest to program) uses the electronic-sheet as a paper-sheet. After any computation, sage freezes the cell, and it's possible to copy again this cell in an other bolow but it's impossible to change it. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
