Calculer les coordonées du point M. Les coordonnées de M sont : Les coordonnées de M sont : Changement de repère Dans un repère , on considère les points A, B, C et M. - Si A, B et C ne sont pas alignés, alors ils définissent un autre repère . Les points O(0 ; 0) et A(− b ; a) appartiennent à la droite (D'), donc le vecteur est un vecteur directeur de (D') et de (D). Un point supplémentaire: Si les deux lignes sont en train d'être traitée comme ligne segments, un contrôle supplémentaire est nécessaire pour voir si le point d'intersection se trouve dans les points de fin de chaque ligne. 1 C 1 2 C 2 (avis, comme C la colonne remplace donc la coef. Si les deux plans P et Q sont définis par leur équations cartésiennes : P : ax + by + cz + d = 0. Le tout étant bien entendu de pouvoir le programmer ( en python ). wikiHow est un wiki, ce qui veut dire que de nombreux articles sont rédigés par plusieurs auteurs(es). En remplaçant les x par 2 dans une des deux fonctions, on trouve le y: y = 2 x - 7 ⇔ y = 2 × 2 - 7 ⇔ y = 4 - 7 ⇔ y = -3 On retrouve bien le point d'intersection de coordonnées (2, -3), celui que l'on avait déterminer graphiquement, par lecture graphique. Dans un même plan, deux droites non parallèles ont un point d’intersection. Je suis en train de m'exercer avec un exercice de math et je suis bloqué.
