Homework Statement


Im given two vectors and im told to find theyre unit normal vector.


Homework Equations



a x b

The Attempt at a Solution


I used the cross product of the 2 vectors to find the normal vector, however, it came out to be i + j + k. My question is, is this already a unit vector or do i need to use the equation [tex]\hat{}n[/tex] = n/[tex]\left|n\right|[/tex]?
