To think on saddle point. Why are they given that name? If there is any connection between real saddles, explain it. Concept Introduction: A two dimensional linear system is a system of the form x ˙ = a+by , where a, b,c, d are parameters. A saddle point can be defined as a point on a graph that is neither a local minimum nor a local maximum . At the saddle point, the partial derivatives of x and y are both equal to zero.
