Lecture
This lecture covers the concept of phase plan, focusing on trajectories and isoclines in mechanical systems. The instructor explains how to represent trajectories and analyze the behavior of dynamic systems using isoclines. Different methods, such as Hamilton and Hemittere, are discussed for obtaining phase plan representations. The lecture emphasizes the importance of parameterization and slope selection in accurately depicting trajectories on the phase plan. Various equations and techniques are presented to illustrate the relationship between points and their corresponding vectors in the phase plan.
