Try finding the eigenvectors as well as the eigenvalues as the eigenvectors can tell you the direction of the trajectories

MAT244--Lectures & Home Assignments / Complex eigenvalues
« on: November 07, 2018, 11:19:35 PM »
When I tried some of the questions that involved matrices with complex eigenvalues, I sometimes ended up with matrices whose reduced row echelon forms that have pivot positions on each column (after subracting the main diagonal entries with the eigenvalues; no free variables). Does this sometimes happen whenever I try to find eigenvectors with this?

The results should definitely come before the drop deadline. You will very likely need to know this in order to decide whether to drop the course or not
