Homework Statement
A vector in lR 3 (basis) has vector space V with the standard inner product.
I need to find a vector in V which is perpendicular to both vectors
v_1 = (1,2,1)^T and v_1 = (2,1,0)^T
Homework Equations
There is no real important equations other than just using matrix and linear transformation principles.
The Attempt at a Solution
My attempt has gone nowhere. I used dot product to show the two vectors are not perpendicular and that's about it. It's probably real simple but I just don't get it.
