Pour les fautes, j'ai pas trop regardé mais ça m'a l'air correct. Mais, perso, je mettrai les dates en chiffre. Et il y a des formulations de phrases un peu lourde " Au lieu de dire : ils ont deux filles qui sont jumelle " tu peux dire " ils ont des jumelle qui s'appelle ..." et d'autre exemple dans le texte

Roger Federer is a swiss Tennis player.Roger Federer was born on  August the eighth nineteen eighty one in Basel. His mother , Lynette is south-african and his father Robert Swiss. He's married with a former tenniswoman, Mirka Vavrinec. They have two daughters, who are twins, called Myla Rose and Charlena Riva. I think he's the best player I've ever seen. He've won sixty sevent tiles during his carreer. And I'm sure he can get more than eighty before its end. In the world, he his the second most paid sportsman in the World, just behind golfer Tiger Wood. He began his professionnal carreer in nineteen ninety eight and won his first title in 2001 in Milan.
On the sixth of July Two thousand three, Roger Federer became the first Swiss to win a Great Chlem title : he beat Australian Mark Philipoussis in Wimbledon's final.
On February the second two thousand four he became the top leader at world's men ranking and kept his first place during four seasons before giving the lead in 2008 at his famous ennemy, Rafa Nadal. Two thousand nine was marked by his first victory at RG, the only great chelem which was missing to his credit. But this was also the year he reconquered his first world ranking place. Further, he beat a new record detained previously by American Pete Sampras who had won fourteen great chlem titles; Federer reached his sixteenth. After this, he's seen by all the world as the best player of history. Last year, he lost his first place again for Spanish Rafael Nadal. So Federer missed a new record : the longest player to stay world number one. This year, he was very poor. At first great chelem of the season, theAustralian Open, he lost in semi-final against Serbian Novak Dchokovitsh although he was considered as the favorite to win the tournament. He even lost at RG where he was defeat against Nadal in final. Federer's actual manager is American Paul Annacone. In two weeks, Wimbledon will take place and Federer could add a seventeenth great chelem's title at his credit. Federer is well-known for his fair-play and humility as well on as outside tennis court. Federer is world-famous. He puts a lot of himself into relief agency. In two thousand three, he created the "Fondation Roger Federer" to help disadvantged people and to promote sport in the world. This association supports projects in South Africa, Mali, Ethiopia and encourage young athlets in Switzerland. Federer is also a soccer fan : he's a FC Bâle fan and often goes to Saint-Jacque stadium to see matches of his favorite team.

Merci à moi aussi.

Si les points sont alignés, le produit vectoriel est nul.

Le plan ne te suffit pas ? C'est pas sorcier de remplir un commentaire en ayant le plan. Suffit de relever les remarques correspondantes et d'ajouter les remarques de style.

Si tu parles du produit scalaire c'est que tu fais un gros caca. Si c'est nul c'est que les deux vecteurs sont orthogonaux.

Tu prends les vecteurs FG et FH et tu démontres qu'ils sont colinéaires parce qu'ils ont des coordonnées proportionnelles.

Rom ignorant

Abruti.

Le produit vectoriel de deux vecteurs est nul quand ceux-ci sont colinéaires justement.

Retour à la case Wikipédia.
http://fr.wikipedia.org/wiki/Produit_ve … A9finition

Mais elle est pété ta technique. Tu fais la mienne en trois secondes tu trouves. Colinéarité des vecteurs, trou d'fion.

Tu sais que tes phrases sont comme le produit vectoriel de deux vecteurs colinéaires ?

Retourne parler de la pression atmosphérique en Angleterre depuis dix ans avec SweDen, t'as l'air un peu moins con. Mais toujours un peu quand-même.

Non c'est le tien qui est complètement con. Tu me parles de méthode plus facile alors que la tienne englobe le sinus de l'angle formé par les deux vecteurs, ce qui est super lourd. Ma méthode est 20x plus rapide et facile, c'est tout.

Je vois que ma petite discussion t'as bien plus, si tu me lèches le cul p-t que je pourrais aller t'en faire une sur le ratio pressionatmosphérique/précipitations. En tout cas, c'est plaisant que tu t'en délectes.

C'est cos (u,v) et pas sin (u,v).

Vous allez faire chier longtemps avec le produit scalaire?


T'as juste trois opérations à faire, sinon, pour le produit vectoriel (et pas de sinus en vue, d'ailleurs), pour trouver les trois coordonnées du produit vectoriel, et tu t'arrêtes à la première coordonnée non nulle :

FH (1,-2,-2)
FG (10,7,3)

FGxFH = ( (-2)*3-7*(-2) , (-2)*10-3*1 , 1*7-10*(-2) )

Donc les trois points en sont pas alignés. Sinon, une recherche du coefficient de proportionnalité va bien plus vite.

Et oui, je retravaille un peu en vue de la rentrée

Donc voilà je n'arrive pas a factoriser ce trinôme.

P(x)=x²+7x-8

Si quelqu'un sait mettre ça sous forme canonique, juste le début svp

Merci

Désolé, je ne peux pas t'aider, je n'ai jamais rien compris à sa.
Comment ça prend la tête des exercices comme sa

T'es en quelle classe ?

Non c'est simple, il suffit de trouver la méthode mais moi je l'ai pas ^^
