   A topographical map contains curved lines called contour lines. Each contour line corresponds to the points on the map that have equal elevation (Figure 1). A level curve of a function of two variables [latex]f\,(x,\ y)[/latex] is completely analogous to a counter line on a topographical map.

   Nov 16, 2022 · The level curves (or contour curves) for this surface are given by the equation are found by substituting \(z = k\). In the case of our example this is, \[k = \sqrt {{x^2} + {y^2}} \hspace{0.25in}\hspace{0.25in} \Rightarrow \hspace{0.25in}\hspace{0.25in}{x^2} + {y^2} = {k^2}\]

   Dec 29, 2020 · Given a function \(z=f(x,y)\), we can draw a "topographical map'' of \(f\) by drawing level curves (or, contour lines). A level curve at \(z=c\) is a curve in the \(x\)-\(y\) plane such that for all points \((x,y)\) on the curve, \(f(x,y) = c\).

   One way to collapse the graph of a scalar-valued function of two variables into a two-dimensional plot is through level curves. A level curve of a function $f(x,y)$ is the curve of points $(x,y)$ where $f(x,y)$ is some constant value.

   Sep 29, 2023 · Topographical maps can be used to create a three-dimensional surface from the two-dimensional contours or level curves. For example, level curves of the distance function defined by \(f(x,y) = \frac{x^2 \sin(2y)}{32}\) plotted in the \(xy\)-plane are shown at left in Figure \(\PageIndex{8}\).

   What is a level curve on a topographical map?

   • A level curve of a function of two variables f (x, y) f (x, y) is completely analogous to a counter line on a topographical map. Figure 1. (a) A topographical map of Devil’s Tower, Wyoming. Lines that are close together indicate very steep terrain. (b) A perspective photo of Devil’s Tower shows just how steep its sides are.

   What is a graph of a function of two variables?

   • The graph of a function of two variables is a surface in R3 and can be studied using level curves and vertical traces. A set of level curves is called a contour map. 13.1: Functions of Several Variables is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts.

   What are the equations of level curves?

   • The next topic that we should look at is that of level curves or contour curves. The level curves of the function z =f (x,y) z = f (x, y) are two dimensional curves we get by setting z = k z = k, where k k is any number. So the equations of the level curves are f (x,y) =k f (x, y) = k.

   How do you 'picture' a graph of three variables?

   • There are a few techniques one can employ to try to "picture'' a graph of three variables. One is an analogue of level curves: level surfaces. Given w = f(x, y, z), the level surface at w = c is the surface in space formed by all points (x, y, z) where f(x, y, z) = c.
