Points importants du cours :
Le vecteur est un objet math\u00e9matique repr\u00e9sentant une direction et une distance. Il est repr\u00e9sent\u00e9 par une fl\u00e8che avec une origine et un bout, le bout \u00e9tant la direction. Les vecteurs sont \u00e9galement d\u00e9finis par leur coordonn\u00e9es (x, y) dans un plan.<\/p>\n

Exercice \"\u23f0\" 5 \u00e0 10 minutes :<\/p>\n

Consid\u00e9rons l’espace vectoriel du plan P.
Soient A(2;3) et B(-1;7) deux points dans le plan P. Calculez les coordonn\u00e9es du vecteur AB –> _________________. <\/p>\n

Soit O l’origine des vecteurs dans le rep\u00e8re ORTHONORM\u00c9 (OIJ).
Completer les expressions suivantes avec OI ou OJ :
– Le vecteur unitaire de l\u2019axe des abscisses est not\u00e9 _______ .
– Le vecteur unitaire de l\u2019axe des ordonn\u00e9es est not\u00e9 _______ .<\/p>\n

Bar\u00e8me :
– Calculer le vecteur AB –> : 1 point
– Compl\u00e9tion : chacun pour 0.5 point<\/p>\n

R\u00e9ponses\" :
Les coordonn\u00e9es du vecteur AB sont (-3;4)<\/p>\n

Le Vecteur unitaire de l’axe des abscisses est not\u00e9 OI.
Le Vecteur unitaire de l’axe des ordonn\u00e9es est not\u00e9 OJ.<\/p>\n

Cet exercice s’adapte aux \u00e9l\u00e8ves en leur fournissant la possibilit\u00e9 d’utiliser leurs connaissances sur les coordinateurs d’un espace vectoriel tout misant surtout sur leurs comp\u00e9tences analytiques pour calculer correctement les diff\u00e9rents pars d\u2019un espace vectoriel.<\/p>\n","protected":false},"excerpt":{"rendered":"
