Let each of the following matrices represent an active transformation of vectors in (x,y)plane (axes fixed, vector rotated or reflected). As in Example 3, show that each matrix is orthogonal, find its determinant and find its rotation angle, or find the line of reflection.
Note in Section 6 [see (6.15)] that, for the given matrix A, we found , so it was easy to find all the powers of A. It is not usually this easy to find high powers of a matrix directly. Try it for the square matrix Min equation (11.1). Then use the method outlined in Problem 57 to find.
Show that a real Hermitian matrix is symmetric. Show that a real unitary matrix is orthogonal. Note: Thus, we see that Hermitian is the complex analogue of symmetric, and unitary is the complex analogue of orthogonal. (See Section 11.)
(a) If Cis orthogonal and Mis symmetric, show that is symmetric.
(b) IfC is orthogonal and Mantisymmetric, show thatis antisymmetric.
