I wrote the problem exactly as in the worksheet given.

I think the same. I will perform a solution with a rotation through the z axis and share it here. Thanks!

I have the matrix $$ A = \left(\begin{array}{cc} y^2 & -xy\\ -xy & x^2 \end{array} \right) $$ I know that to prove that the matrix is a tensor, it transform their elements in another base. But I still without how begin this problem. Help please! Thanks.
