@Amzoti No, not yet I haven't tried the problem over the last week though since I was on a vacation.

comment Liapunov Function for a Differential Equation
@smanoos If you meant $V(x) = x_1^2 + x_2^2$, then I'm not able to make it work, you get $\dot{V}(x) = 2x_1^3 + 2x_2^3$.

@sos440 What can I do to get as good as you at recognizing integrals? I have tried everything except changing my name to sos450.
