   Dec 29, 2020 · A function of one variable is a curve drawn in 2 dimensions; a function of two variables is a surface drawn in 3 dimensions; a function of three variables is a hypersurface drawn in 4 dimensions. There are a few techniques one can employ to try to "picture'' a graph of three variables.

   Sep 29, 2023 · A level curve of a function \(f\) of two independent variables \(x\) and \(y\) is a curve of the form \(k = f(x,y)\text{,}\) where \(k\) is a constant. A level curve describes the set of inputs that lead to a specific output of the function.

   Example 1. Let $f(x,y) = x^2-y^2$. We will study the level curves $c=x^2-y^2$. First, look at the case $c=0$. The level curve equation $x^2-y^2=0$ factors to $(x-y)(x+y)=0$. This equation is satisfied if either $y=x$ or $y=-x$. Both these are equations for lines, so the level curve for $c=0$ is two lines.

   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 function?

   • Find and graph the level curve of the function g(x, y) = x2+y2 −6x+2y g (x, y) = x 2 + y 2 − 6 x + 2 y corresponding to c = 15 c = 15. Another useful tool for understanding the graph of a function of two variables is called a vertical trace.

   What is the relationship between a level curve plot and a graph?

   • When you drag the green point to the right, each level curve f(x, y) = c f (x, y) = c moves to the height z = c z = c, so that they are in the same position as in the graph of z = f(x, y) z = f (x, y). In this way, the figure demonstrates the correspondence between the level curve plot and the graph of the function. More information about applet.

   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.

   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.

    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.
