Applied Dynamical Systems - ME215A Fall 2010 Homework 6 - Due Wednesday November 10 - in class 1. (20 pts total) Consider the vector ﬁeld ˙ x = y - 3 x 2 + xy, (1) ˙ y = - 3 y + y 2 + x 2 . (2) (a) (5 pts) What are the eigenvalues of the ﬁxed point at the origin? Find a linear coordinate transformation ± x y ! = S ± u v ! (3) so that the linear part of the equations in the new coordinates ( u, v ) is diagonal, with
