Hi Anders,

You can define it for yourself or easier use one of the packages coming
with Mma:

      Needs["Calculus`VectorAnalysis`"]
here the command is "CrossProduct"

or use

      Needs["LinearAlgebra`CrossProduct`"]

with the Command "Cross"

e.g.:

      Cross[{a1, a2, a3}, {b1, b2, b3}]

For more help to these packages see "Guide to Standard Mathematica
Packages" or the online help. 

Kind regards, Harald
