  • The correct solution is trivially clear, surely. As Barkley Rosser puts it in his outstanding clarification of the issue, "Aspects of dialectics and non-linear dynamics" (available on the crashlist website):
     
    "Consider a general family of n differential equations whose behaviour is determined by a k-dimensional control parameter m , such that 
    x/dt=fm (x); xX Rn , mX Rk (1)
    with equilibrium solutions given by
    fm (x)=0 (2)
    Bifurcations will occur at singularities where the first derivative of fm (x) is zero and the second derivative is also zero, meaning that the function is not at an extremum, but is rather at a degeneracy. At such points structural change can occur, as an equilibrium can bifurcate into two stable and one unstable equilibria. "
     
    Hope this helps.
