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 Level curves will help you reduce a dimension by treating the function value as a constant That is, the level curves (more correctly "level surfaces") for for f (x,y,z)= 4x^2 y^2 9z^2 will be the three dimensionl graphs 4x^2 y^2 9z^2= C for different values of C Those will be a number of ellipsoids, of different sizes, one inside the otherIe the level curves of a function are simply the traces of that function in various planes z = a, projected onto the xy plane The example shown below is the surface Examine the level curves of the function Sliding the slider will vary a from a = 1 to a = 1

A level curve of f ( x, y) is a curve on the domain that satisfies f ( x, y) = k It can be viewed as the intersection of the surface z = f ( x, y) and the horizontal plane z = k projected onto the domain The following diagrams shows how the level curves f ( x, y) = 1 1 − x 2 − y 2 = k changes as k changesContour plots An alternative method to representing multivariable functions with a twodimensional input and a onedimensional output, contour maps involve drawing purely in the input space Created by Grant Sanderson This is the currently selected itemLevel Curves and Cross Sections Main Concept A level curve of the surface is a twodimensional curve with the equation , where k is a constant in the range of f A level curve can be described as the intersection of the horizontal plane with the surface
