Using cross product to determine if vectors are parallel

  1. Oct 19, 2011 #1
    My question is simple:

    I understand that if u x v = 0 , then u and v are parallel, but what does that 0 mean?
    You can't obtain 0 by crossing two vectors. By 0, does it mean (0,0,0)?

    Yes, it means the zero vector, (0,0,0) .
