Answer:

[√3/3, -√3/3, √3/3]^T

Explanation:

You want a unit vector that is orthogonal to both u= [1,1,0]^T and v = [-1,0,1]^T.

Orthogonal

The cross product of two vectors gives one that is orthogonal to both.

w = u×v = [1, -1, 1]^T

Unit vector

A vector can be made a unit vector by dividing it by its magnitude.

w/|w| = [1/√3, -1/√3, 1/√3]^T = [√3/3, -√3/3, √3/3]^T

__

Additional comment

The ^T signifies the transpose of the vector, making it a column vector instead of a row vector.
