Answer part 1 of the DE problem

(1) A certain system of differential equations has straight line solutions along y = x, y = -x with associated
exponents e3 and e', respectively. Sketch the phase plane for this system. Include any evident features
based on the available information, as well as a few prototypical solution curves, noting end behavior.
(2) A different system of differential equations has straight line solutions along y = x and y = -x with ex-
ponents e-t and e-21, respectively. Sketch the phase plane for this system. Include any evident features
based on the available information, as well as a few prototypical solution curves, noting end behavior.
Reach: Explain how the equilibrium solutions in (1) and (2) differ from one another. Then give an example
of a system that has a qualitatively different equilibrium solution from both of these examples. You may
define aspects or features of the system, such as its solutions (as above), rather than defining the system
explicitly.
