2x2 Systems of ODEs: Saddle Points and Instability
This video investigates a 2-dimensional linear system of ordinary differential equations with a positive and a negative real eigenvalue. These solutions are known as unstable saddle points. Saddle points are extremely useful for energy-efficient transport, including for bipedal walking and locomotion, for fight jets, and also for interplanetary transport. We investigate the solutions using eigenvalues and eigenvectors, as well as with phase portrait pictures.
