1. The problem statement, all variables and given/known data Plot the phase plane of: y(t) = e-6t(2 1) + e-3t(1 -1) 2. Relevant equations 3. The attempt at a solution I know it's a sink because [tex]\lambda_2 < \lambda_1 < 0[/tex]. http://img35.imageshack.us/img35/8108/sink.th.jpg [Broken] but the phase plane in the answer is slanted to the right. Does anyone know why?
