Help, Loi Normale

Bonjour à tous,

j'ai une question hyper urgente, je suis à la bourre.

J'ai un nombre d1=0.25

et je dois trouver selon la loi normale LOI.NORMALE(0.25;0;1;VRAI()) ( --> Excell ) = 0.6

Comment faire cela en javascript ou en php ???

SVP toute aide venu avant ce soir sera providentielle

Merci

Nicolas

Salut
juste une idée comme ça : tu copies la table de la loi normale dans un tableau en javascript ( http://fr.wikisource.org/wiki/Table_...e_r%C3%A9duite )
Après tu n'as plus qu'à faire une fonction de décomposition de ton entrée (0.25 => ligne 0.2 colonne 5 => 0.59871) pour déterminer la bonne valeur.

A+

Super

Super merci du début ( je ne savais pas que cela marchait comme ça loi normale, les souvenirs sont lointain ... )

A tout hasard, si quelqu'un possede ce tableau en javascript déja fait ça serait super

Si quelq'un en a besoin
