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. The average size of a golf cart is just under 4 feet wide by just under 8 feet in length.$\begingroup$ @Federico The issue is that I am having a difficult time grasping the definitions in the study material assigned to me in class.
