The transformation is represented by the matrix A, where A =
(1) Find the eigenvectors of A.
(2) Find an orthogonal matrix P and a diagonal matrix D such that
(3) Hence describe the transformation as a combination of geometrical transformations, stating clearly their order.
I got the answer for question (1) and (2), but I don't get question (3).
Please help! My exam is next week. Thanks.
