32. The system of differential equations is Solution of the system requires analysis of the eigenvalue problem
.
The characteristic equation is
, with roots
and
. With
, the equations reduce to
. A corresponding eigenvector is given
by
Setting
, the system reduces to the equation
.
An eigenvector is
Hence the general solution is The eigenvalues are distinct and both
We find that the equilibrium point
is a stable node. Hence all solutions converge to
33 . Solution of the ODE requires analysis of the algebraic equations ________________________________________________________________________

The characteristic equation is The eigenvectors are real and distinct, provided that the discriminant is positive.
That is,
,
which simplifies to the condition
. . The parameters in the ODE are all positive. Observe that the sum of the roots is Also, the product of the roots is It follows that both roots are negative. Hen...
