Review for "Introduction des notions sinus et cosinus d'un angle"

Introduction des notions sinus et cosinus d'un angle

Global comment:

Review filed on 2010/10/13 00:44 by messaoudadouridj.

Une bonne activité d'introduction des fonctions trigonométriques.Elle amène l'élève à explorer, à expérimenter ,à remarquer ce qui varie de ce qui ne varie pas .L'activité est idéale dans la géometrie dynamique puisque l'élève utilise plusieurs cas de figures pour tirer des conclusions ,très contraignante ,avec des incertitudes de mesures si il fait cette activité en papier-crayon -rapporteur.
This review is done without a trial in classroom.
