    but the dot product of (1,0,1) and (0,1,1) is 1, not 0

    Your questions don't same to have enough info to work with. Where are you getting these questions? from a book? making them up for practice?

    (0,-1,1) should work

    So share with us. How did you determine <0,-1,1>

    wouldn't (0,1,1)*(0,-1,1) = 0?

    It may very well be. I am asking how did you find it?

    So if you were instructing someone, you would tell them make a guess and then test it to see if it so?

    you saay let vector v=(v1,v2,v3) such that u dot v=0*v1+1*v2+1*v3=0 any vector v that satisfies that equation is orthogonal to (0,1,1)
