WebSaddle points of a multivariable function are those points in its domain where the tangent is parallel to the horizontal axis, but this point tends to be neither a local maximum nor a local minimum. For a two-variable function f (x, y), its saddle point is defined as. If z = f (x, y), then the point (x, y, z) is said to be a saddle point if ... WebClassifying critical points. In the last slide we saw that. Critical points are places where ∇ f = 0 or ∇ f does not exist. Critical points are where the tangent plane to z = f ( x, y) is horizontal or does not exist. All local extrema are critical points. Not all critical points are local extrema. Often, they are saddle points.
