In each of Problems 1 through 20:
(a) Determine all critical points of the given system of equations.
(b) Find the corresponding linear system near each critical point.
(c) Find the eigenvalues of each linear system. What conclusions can you then draw about the
nonlinear system?
(d) Draw a phase portrait of the nonlinear system to confirm your conclusions, or to extend them
in those cases where the linear system does not provide definite information about the nonlinear
system.
(e) Draw a sketch of, or describe in words, the basin of attraction of each asymptotically stable
critical point.
