bonjour,

j'ai un doute dans les coordonn=C3=A9es sph=C3=A9riques sur les cas extr=C3=
=AAmes.
Certains sites de conversion math=C3=A9matique donnent une erreur pour ces =
cas extr=C3=AAmes de vecteurs.

Donnez-moi SVP les coordonn=C3=A9es sph=C3=A9riques des vecteurs suivants:
a) (1,0,0)
b) (0,1,0)
c) (0,0,1)
d (-1,0,0)
e) (0,-1,0)=20
f) (0,0,-1)

merci de votre aide
