From Anton, I have this simple looking LA question:
Find all unit vectors parallel to the yz plane that are perpendicular to the vector 3,1,-2
Since this vector is sloped in all 3 dimensions, and since yz is I flat in the x dimension, I am baffled how this can have a solution.
I found a near exact version of this question on another forum but the vector given did have a zero component.
I'm clearly missing some obvious detail, a quick point out would be much appreciated.
