   Mar 2, 2022 · Let us use the function $f(x,y)=x^3+5 x^2+x y^2-5 y^2$ and check wether it has critical points using level curves. In the first step, let us draw the level curves (blue) and the derivatives $\frac{\partial f}{\partial x}$ and $\frac{\partial f}{\partial y}$ (green).

   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.

   level curves. A level curve is just a 2D plot of the curve f (x, y) = k, for some constant value k. Thus by plotting a series of these we can get a 2D picture of what the three-dimensional surface looks like. In the following, we demonstrate this.

   What data can you infer from a level curve?

   • 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. If the function is a bivariate probability distribution, level curves can give you an estimate of variance.

   What is a level curve?

   • The level curves give you a good idea of where the extrema of your function are... Another name for that is the contour line , contour plot or Equipotential Curve: A curve in two dimensions on which the value of a function f (x,y) is a constant. Other synonymous terms are isarithm, isopleth, and contour line.

   How do you get a level curve from a function?

   • Suppose I have a function z = f(x, y) z = f ( x, y), say like z = x2 +y2− −−−−−√ z = x 2 + y 2. By fixing some value for z z and varying all possible x x and y y, we would get a level curve of z = f(x, y) z = f ( x, y). By changing values for z z, one can get different level curves.

   What are contour lines & level curves?

   • Contour Lines: Contour lines are synonymous with level curves and indicate the elevation or value of a function at specific points on a graph, helping to visualize the landscape of a function. Level curves are the curves on a graph representing all points where a multivariable function has the same constant value.

   What is a level curve plot?

   • A function has many level curves, as one obtains a different level curve for each value of c c in the range of f(x, y) f (x, y). We can plot the level curves for a bunch of different constants c c together in a level curve plot, which is sometimes called a contour plot.

    A level curve of a function $f(x,y)$ is the curve of points $(x,y)$ where $f(x,y)$ is some constant value. A level curve is simply a cross section of the graph of $z=f(x,y)$ taken at a constant value, say $z=c$. A function has many level curves, as one obtains a different level curve for each value of $c$ in the range of $f(x,y)$.
