(a) Find a basis for the eigenspace E-1 of A associated to the eigenvalue λ = -1 BE-1 -2 4 -2 0 (b) Find a basis of the eigenspace E-2 of A associated to the eigenvalue λ = -2. BE-27 40B Observe that the matrix A is diagonalizable. WebThe eigenvalues of a skew symmetric matrix are either zero or imaginary values. The real eigenvalue of a real skew symmetric matrix A, λ equal zero, that means the nonzero eigenvalues of a skew-symmetric matrix are non-real. Proof: Let A be a square matrix and λ be an eigenvalue of A and x be an eigenvector corresponding to the eigenvalue λ.

Web10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment.
