	problème de trigonométrie		2005-11-01
		Manon pose la question : Soit un triangle ABC, de cotes a , b et c, avec A=45° et B=60°. Apres avoir demontre que 3a²-2b²=0 (que jai fais en utilisant la regle du sinus) et a²-2c²+2ac=0 (que jai fait en utilisant la regle du cosinus), vous montrerez que laire du triangle ABC peut sexprimer: { [ 3 + racine carre 3 ] / 12 } b² unites. Je ne sais pas comment arriver a cette expression de laire. Je narrive pas a exprimer c² et ac en fonction de b².. et je pense que ca pourrait vraiment aider.. puisque je suis arrive a letape: ac[(racine carre 3) / 4] avec ac = a² + c² - b² et a² = 2/3 b² ms c²= 1/3 b² + ac Claude Tardif lui répond.
