   Level Curves. 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 .

   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.

   Level curves. 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.

   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.

   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 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 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.

   • 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. This is essentially an animation that you can go through step by step.

   How do you find a level curve?

   • Example 3 Identify the level curves of f (x,y) = √x2 +y2 f (x, y) = x 2 + y 2. Sketch a few of them. Note that we can think of contours in terms of the intersection of the surface that is given by z = f (x,y) z = f (x, y) and the plane z =k z = k. The contour will represent the intersection of the surface and the plane.

   Dec 29, 2020 · A level curve at \(z=c\) is a curve in the \(x\)-\(y\) plane such that for all points \((x,y)\) on the curve, \(f(x,y) = c\). When drawing level curves, it is important that the \(c\) values are spaced equally apart as that gives the best insight to how quickly the "elevation'' is changing.
