(1 point) Consider the differential equation dx = Ax(t) dt where A is a given matrix. Determine whether the equilibrium (0, 0) is a stable spiral, an unstable spiral, or a neutral spiral (center). Also determine whether the trajectories travel clockwise or counterclockwise. A = The equilibrium (0, 0) is ? C Trajectories travel ? 5 9 A = -36 The equilibrium (0, 0) is ? C Trajectories travel ? 4 -9 A = 31 The equilibrium (0, 0) is ? Trajectories travel ? C
