Comments: All of the papers submitted were correct and shown clearly.
D-white's paper, however, was all computer generated and therefore was
better for publication.
 

GRADER'S AND INSTRUCTOR'S COMMENTS:  Notice that (a) diverges from the 
origin; (b) converges to y = x and diverges from y = -x; (c) curls around 
the origin.  In case (b), the lines y = x and y = -x are called the stable 
and unstable manifolds, respectively, of the hyperbolic fixed point at the 
origin.  In (c), the fixed point is called elliptic.
