Chapter 5.2, Problem 12E
Interpretation Introduction

Interpretation:

Write the system equation in two-dimensional linear system. Show that for R>0, the origin is asymptotically stable and it is neutrally stable if R=0. For R2C4L positive, negative, or zero, classify the fixed point at the origin, and plot the phase diagram.

Concept Introduction:

A two dimensional linear system can be expressed in the form as

x˙=ax+byy˙=cx+dy

Here a, b, c, d are parameters. This linear system can be represented in the matrix form as

x˙=Ax

Here the matrix x˙ is represented as

x˙ = [x˙y˙] and A=(abcd)

[x˙y˙]=(abcd)(xy)

(b) Let I[y] be a functional of y(x) defined by [[y] = √(x²y' + 2xyy' + 2xy + y²) dr, subject to boundary conditions y(0) = 0, y(1) = 1. State the Euler-Lagrange equation for finding extreme values of I [y] for this prob- lem. Explain why the function y(x) = x is an extremal, and for this function, show that I = 2. Without doing further calculations, give the values of I for the functions y(x) = x² and y(x) = x³.
