Thanks to all who replied, especially to David Park, Andrzej Koslowski and
Jean-Mark Gulliet.
As Jean-Mark pointed out, it works correctly in version 5.2!
Yes, I had loaded the Vector Analysis package, set coordinates to
cylindrical, and the components of the vectors were the cylindrical
coordinates.
In version 5.1,
DotProduct[{1,Pi/4,0},{2,0,1}]
Out: Sqrt[2]
In version 5.2,
DotProduct[{1,Pi/4,0},{2,0,1}]
Out: 2
It seems Wolfram made some changes in this respect.
Thanks again
Sergio Terrazas
