    To find a vector which is perpendicular to 2 others, just find the cross product between the two.

    Let A(1,-1,2) and B(2,1,-3).

    A x B will be perpendicular to both vectors A and B.
    (I hope you know to find cross product)

    To find unit vector just divide the resultant with the norm.
