Chapter 5.2, Problem 5E
Interpretation Introduction

Interpretation:

Find the characteristic polynomial for the system of linear equations x˙ =  3x- 4y and y˙ = x -y using x˙ = Ax equation. Also, determine the eigenvalues and eigenvectors of matrix A.

To find the general solution for the given system of linear equations.

Classify the fixed points at the origin.

Concept Introduction:

For two dimensional linear systems, equations are x˙ = ax + by, y˙ = cx + dy

Above linear system expressed in the form x˙ = Ax.

The standard characteristics polynomials is,

λ2- τλ + Δ = 0, where τ is the trace of matrix A, λ is the corresponding eigenvalue, and Δ is determinant of matrix A.

(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.
