Given a function f of two variables x and y, these may be found by finding points such that the square of fxy ["f sub ecks why"] is greater than the product of fxx ["eff sub ecks ecks"] and fyy ["eff sub why why"]. An example is the center of a hyperbolic paraboloid, since restricting the graph to one plane makes the center a maximum, while restricting the graph to a second plane makes the center a minimum. They may be defined as critical points that are not local extrem

They may be defined as critical points that are not local extrema. For ten points, what are these points named because their graphs in 3-space often resemble a piece of equipment used to ride a horse?
