When the level curves are spaced far apart (in the center), there is a gradual change in the function values When the level curves are close together (near c = 5), there is a steep change in the function values 25 Example 7 Sketch a contour map of the function, using the level curves at c = 0, 2, 4, 6 and 8I've a plot of a 3D function of 2 variables and I'm interested into extrapolating the curve that I would like to obtain the level curves of a given function z=f(x,y) without using the countours function in the Matlab environment By letting Z equal to some constant 'c' we get a single level curve I would like to obtain an expression of the resulting function of the form y=f(x) to be able to study other properties of it Basic Example 1 Easy game

Graphs and level curves of functions of two variables
Graphs and level curves of functions of two variables-Def If f is a function of two variables with domain D, then the graph of f is {(x,y,z) ∈ R3 z = f(x,y) } for (x,y) ∈ D Def The level curves of a function f(x,y)are the curves in the plane with equations f(x,y)= kwhere is a constant in the range of f The contour curves are the correspondingFollow 2 views (last 30 days) Show older comments Giuseppe on Vote 0 ⋮ Vote 0 Edited Matt J on Accepted Answer Matt J Hi guys!

Section 125 Functions of Three Variables Representing a Function of Three Variables using a Family of Level Surfaces Just as we could plot a family of level curves (a contour diagram) for a function f(x;y) of two variables, we can \plot" a family of level surfaces for a function of three variables w = f(x;y;z)One primary difference, however, is that the graphs of functions of more than two variables cannot be visualized directly, since they have dimension greater than three However, we can still use slice curves, slice surfaces, contours, and level sets to examine these higherdimension functions Definition level curves Given a function f(x, y) and a number c in the range of f, a level curve of a function of two variables for the value c is defined to be the set of points satisfying the equation f(x, y) = c Returning to the function g(x, y) = √9 − x2 − y2, we can determine the level curves of this function
Level Surfaces It is very difficult to produce a meaningful graph of a function of three variables A function of one variable is a curve drawn in 2 dimensions; A level curve (or contour) of a function \(f\) of two independent variables \(x\) and \(y\) is a curve of the form \(k = f(x, y)\), where \(k\) is a constant Topographical maps can be used to create a threedimensional surface from the twodimensional contours or level curves19 Level Curves A second way to visualize a function of two variables is to use a scalar field in which the scalar z = f(x, y) is assigned to the point (x, y)A scalar field can be characterized by level curves (or contour lines) along which the value of f(x, y) is constant For instance, the weather map

As in this example, the points (x, y) such that f (x, y) = k usually form a curve, called a level curve of the function A graph of some level curves can give a good idea of the shape of the surface;Picturing f(x;y) Contour Diagrams (Level Curves) We saw earlier how to sketch surfaces in three dimensions However, this is not always easy to do, or to interpret A contour diagram is a second option for picturing a function of two variables Suppose a function h(x;y) gives the height above sea level at the point (x;y) on a map Here is a set of practice problems to accompany the Functions of Several Variables section of the 3Dimensional Space chapter of the notes for Paul Dawkins Calculus III course at Lamar University 7 identify and sketch the level curves (or contours) for the given function \(2x 3y {z^2} = 1\) Solution \(4z 2{y^2} x = 0\) Solution
