In the present study, the students who formed the discussion group were teachers at the "preparatory" level on different campuses of the Instituto Tecnológico The reason we chose to present on-line student exchanges on this specific problem In what follows we extract only those parts of messages that correspond to the particular problem presented above, although the group was discussing several	./cache/work_ahyleqfxcrdw7l3eqsu2z5rf7q.pdf	./txt/work_ahyleqfxcrdw7l3eqsu2z5rf7q.txt
