Chapter , Problem 19

(choose chapter or problem)

Consider the second-order equation

\(\frac{d^{2} y}{d t^{2}}+p \frac{d y}{d t}+q y=0\),

where p and q are positive.

(a) Convert this equation into a first-order, linear system.

(b) Compute the characteristic polynomial of the system.

(c) Find the eigenvalues.

(d) Under what conditions on p and q are the eigenvalues two distinct real numbers?

(e) Verify that the eigenvalues are negative if they are real numbers.
