Consider the following. A = 412979 3 Find all eigenvalues 2 of the matrix A. (Enter your answers as a comma-separated list.) = -1 X Give bases for each of the corresponding eigenspaces. (Enter sqrt(n) for n.) -1/sqrt(3) smaller 2-value span T larger 2-value span 1 sqrt(3) 1 Orthogonally diagonalize the matrix by finding an orthogonal matrix Q and a diagonal matrix D such that QTAQ = D. (Enter each matrix in the form [[row 1], [row 2],...], where each row is list.) (D, Q) = -(
