## Homework Statement

You are given that with x = (x

_{1},x

_{2}), y = (y

_{1},y

_{2}), the formula

(x,y) = [x1 x2] [2 1;1 2] [y1;y2] (where ; represents a new row).

is a inner product for the vectors in R

^{2}

Using this inner product, find a unit vector perpendicular to the vector (1,1)

## Homework Equations

## The Attempt at a Solution

I don't particularly understand what a perpendicular unit vector has to do with the inner product, I can find a perpendicular unit vector in the normal dot product way however I don't know how to find one using the inner product, any help would be much appreciated,

Thanks in advanced
