Hi everyone,
 
I have some weird problems in using Mathematica to do some vector analysis...perhaps its my lack of knowledge :) but i want to be sure.
 
Needs["Calculus'VectorAnalysis' "]
SetCoordinates[Cylindrical[r,phi,z]];
 
I want to check that the cross product of the basis vector z and r give phi, i.e :
 
CrossProduct[{1,0,0},{1,0,0}]  = {1,Pi/2,0} 
 
Why this result ?
 
Does a vector in cylindrical coordinates be {Ar, Aphi, Az} ?
 
Thanks for your help.
