Computer problem:

A) numerically integrate the simple harmonic oscillator:  generate one phase space figure, where you plot at least three trajectories with different initial conditions. 

B) numerically integrate the Van der Pol oscillator [Eq. (2)  in chapt. 7]: generate one phase space figure, where you plot at least three trajectories with different initial conditions. 

C) discuss the difference between A) and B)
