   Sep 29, 2023 · The traces and level curves of a function of two variables are curves in space. In order to understand these traces and level curves better, we will first spend some time learning about vectors and vector-valued functions in the next few sections and return to our study of functions of several variables once we have those more mathematical ...

   Sketch several traces or level curves of a function of two variables. If hikers walk along rugged trails, they might use a topographical map that shows how steeply the trails change. 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).

   What is a level curve?

   • A level curve (or contour) of a function f of two independent variables x and y is a curve of the form k = f (x,y)ext {,} where k is a constant. Topographical maps can be used to create a three-dimensional surface from the two-dimensional contours or level curves.

   How do you find the level curve of a topographical map?

   • Notice the top of the tower has the same shape as the center of the topographical map. Given a function f (x, y) f (x, y) and a number c c in the range of f f, a level curve of a function of two variables for the value c c is defined to be the set of points satisfying the equation f (x, y) =c f (x, y) = c.

   How to define level surfaces for a function of 3 variables?

   • Functions of two variables have level curves, which are shown as curves in the xy − plane. However, when the function has three variables, the curves become surfaces, so we can define level surfaces for functions of three variables.
