By combining the level curves f (x, y) = c for equally spaced values of c into one figure, say c = − 1, 0, 1, 2, , in the x y plane, we obtain a contour map of the graph of z = f (x, y) Thus the graph of z = f (x, y) can be visualized in two ways, one as a surface in 3 space, the graph of z = f (x, y),Show that the level curves of the cone {eq}z = (x^2 y^2)^{\dfrac 1 2} {/eq} and the paraboloid {eq}z = x^2 y^2 {/eq} are circles Level Curves To solve thisLevel Curves of a Paraboloid This example requires WebGL Visit getwebglorg for more info When we lift the level curves up onto the graph, we get "horizontal traces"

Mathematical discussion A simple criterion for checking if a given stationary point of a realvalued 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 pointFor example, the Hessian matrix of the function = at the stationary point (,,) = (,,) is the matrixA hyperbolic paraboloid (not to be confused with a hyperboloid) is a doubly ruled surface shaped like a saddleIn a suitable coordinate system, a hyperbolic paraboloid can be represented by the equation 6 = In this position, the hyperbolic paraboloid opens downward along the xaxis and upward along the yaxis (that is, the parabola in the plane x = 0 opens upward and the parabola The level curves are parabolas of the form x2 = zo B The level curves are lines of the form x y =
