1 Answer. Sorted by: 2. If 0 0 is an eigenvalue for the linear transformation T: V → V T: V → V, then by the definitions of eigenspace and kernel you have. V0 = {v ∈ V|T(v) = 0v = 0} = kerT. V 0 = { v ∈ V | T ( v) = 0 v = 0 } = ker T. If you have only one eigenvalue, which is 0 0 the dimension of kerT ker T is equal to the dimension of ...Or we could say that the eigenspace for the eigenvalue 3 is the null space of this matrix. Which is not this matrix. It's lambda times the identity minus A. So the null space of this matrix is the eigenspace. So all of the values that satisfy this make up the eigenvectors of the eigenspace of lambda is equal to 3.The dimensions of a golf cart can vary slightly depending on the manufacturer, model and options added.

Nov 14, 2014 at 5:48. Thank you!Therefore, (λ − μ) x, y = 0. Since λ − μ ≠ 0, then x, y = 0, i.e., x ⊥ y. Now find an orthonormal basis for each eigenspace; since the eigenspaces are mutually orthogonal, these vectors together give an orthonormal subset of Rn. Finally, since symmetric matrices are diagonalizable, this set will be a basis (just count dimensions).Since $(0,-4c,c)=c(0,-4,1)$ , your subspace is spanned by one non-zero vector $(0,-4,1)$, so has dimension $1$, since a basis of your eigenspace consists of a single vector.
