Exemple de sortie écran :

    f :  x,y,z -> (x*y*z)

 The change of variables.
 X     :  r,k,z -> (r*cos(k))  			   
 Y     :  r,k,z -> (r*sin(k))  			   
 Z     :  r,k,z -> (z)  			 

 The cylindrical coordinates.
 z1   r,k   -> r  
 z0   r,k   -> 0

 r1     k   -> 1  
 r0     k   -> 0

 k1         -> PI/2
