Chapter 6.8, Problem 9E

Interpretation Introduction

Interpretation:

To tell whether it is true or false that there exists at least one fixed point between the spaces of two closed trajectories.

Concept Introduction:

The fixed point of a differential equation is a point where, $\text{f(x*) = 0 ; while substitution f(x*) = }\dot{\text{x}}\text{ is used and x\&*\#x00A0;is a fixed point}$

Trajectories in a phase plane represent the evolution of the system with respect to time and change in parameters.
