You can infer all sorts of data from level curves, depending on your function. The spacing between level curves is a good way to estimate gradients: level curves that are close together represent areas of steeper descent/ascent.
Mar 2, 2022 · In the first step, let us draw the level curves (blue) and the derivatives ∂f ∂x ∂ f ∂ x and ∂f ∂y ∂ f ∂ y (green). Intersections of both green curves are critical points, which are in our case (0, 0) (0, 0) and (−3.33, 0) (− 3.33, 0): The code (Mathematica) for this is: F[x_, y_] = x^3 + 5 x^2 + x*y^2 - 5 y^2; Fx[x_, y ...

Given a function [latex]f\,(x,\ y)[/latex] and a number [latex]c[/latex] in the range of [latex]f[/latex], a level curve of a function of two variables for the value [latex]c[/latex] is defined to be the set of points satisfying the equation [latex]f\,(x,\ y)=c[/latex].

We can put the tails of our vectors on the curve itself to get picture that's a little easier to work with: What do you notice about the magnitude of the gradient vector at x=0?

Level curves help visualize how a function behaves over its domain by representing points with equal output values. In two-variable functions, level curves can be used to identify contours that separate regions of different values, providing insight into function behavior.
