Thread: Finding unit vectors perpendicular to points.

Find unit vectors perpendicular to a = (1, 3, -1) and b = (2, 0, 1).

I understand that the cross product of two vectors will give a vector that is perpendicular to them. So I did the cross product and I have 3i - 3j - 6k.

How do I find more vectors that are perpendicular?

Here are the two unit vectors:

How do you know that those vectors are perpendicular, and does 3i - 3j - 6k count?
