WebMathematical discussion. A simple criterion for checking if a given stationary point of a real-valued function F(x,y) of two real variables is a saddle point is to compute the function's Hessian matrix at that point: if the Hessian is indefinite, then that point is a saddle point.For example, the Hessian matrix of the function = at the stationary point … WebAn inflection point is defined as a point on the curve in which the concavity changes. (i.e) sign of the curvature changes. We know that if f ” > 0, then the function is concave up …

"WebPutting all this together, we can deduce that the stationary point at x =0is a relative maximum. Since dy dx > 0 for x<0, dy dx =0for x , and dy dx < 0 for x>0, we have a relative maximum at x =0. The graph of y = −x2 +1. We can sum this information up in a table that allows us to see at a glance that the point (0,1) is a maximum. x < 0 0 > 0 ... " - How can you tell if a point is stationary
