I just would have said I and Z initially, since you can't do much more to simplify a diagonal matrix. A diagonal matrix is a square matrix with all its elements (entries) equal to zero except the elements in the main diagonal from top left to bottom right. An orthogonal matrix is the real specialization of a unitary matrix, and thus always a normal matrix.Although we consider only real matrices here, the definition can be used for matrices with entries from any field.However, orthogonal matrices arise naturally from dot products, and for matrices of complex numbers that leads instead to the unitary requirement. As a hint, I'll take the determinant of a very similar two by two matrix. In these notes, we will compute the eigenvalues and eigenvectors of A, and then find the real orthogonal matrix that diagonalizes A. To find the invertible matrix S, we need eigenvectors.
