In contrast, the goal of the theory of dynamical systems is to understand the behavior of the whole ensemble of solutions of the given dynamical system, as a function of either initial conditions, or as a function of parameters arising in the system.
Since dynamical systems is usually not taught with the traditional axiomatic method used in other physics and mathematics courses, but rather with an empiric approach, it is more appropriate to use a practical teaching method based on projects done with a computer.
