WebWith vectors, you don't have such a "unit". There is no vector 1 → such that the cross product of 1 → with any other vector x → is x →, that is, 1 → × x → = x →. So that is way we don't really have a division of vectors that "works" just like division of real numbers do. Share Cite Follow edited Jul 4, 2024 at 21:59 Arunabh Bhattacharya 33 12
