            The coefficient matrix of 2-dimensional linear differential equation systems has complex eigenvalues and eigenvectors if and only if there are lines of attraction. The proof arose from and makes use of a graphical field plot representation of such systems. The use of Mathematica for both algebraic calculation and generation of these field plots allowed the proof to arise quite naturally.
