Hi
We have a linear transformation g : ℝ^2x2 → ℝ g has U as kernel,
U: the 2x2 symmetric matrices
(ab)
(bc)
A basis for U is
(10)(01)(00)
(01)(10)(01)I thought this would be easy but I've been sitting with the problem for a while and I have no clue on how to solve it (maybe because I don't fully understand it).
But this is how I understand it : we need to find a linear transformation that transforms symmetric 2x2 matrices (R^4) to 1x1 matrices (R), so we have
g(a,b,b,c) = (a b b c) = 0
?
