I am not sure how I should explain the following problems:
If you take any two perpendicular unit vectors X and Y, then
1. X\[Cross]Y is perpendicular to both X and Y
2. X\[Cross]Y is also a unit vector
3. If X and Y are unit vectors, but X is not perpendicular to Y, then can X\[Cross]Y be a unit vector? Why not?
