The range of g g is the closed interval [0, 3] [0, 3]. First, we choose any number in this closed interval—say, c =2 c = 2. The level curve corresponding to c = 2 c = 2 is described by the equation. √9−x2 −y2 = 2 9 − x 2 − y 2 = 2. To simplify, square both sides of this equation: 9−x2 −y2 = 4 9 − x 2 − y 2 = 4.
Nov 16, 2022 · Section 12.5 : Functions of Several Variables. In this section we want to go over some of the basic ideas about functions of more than one variable. First, remember that graphs of functions of two variables, z = f (x,y) z = f (x, y) are surfaces in three dimensional space. For example, here is the graph of z =2x2 +2y2 −4 z = 2 x 2 + 2 y 2 − 4.
Example 2. Let f(x, y, z) = x2 +y2 +z2 f (x, y, z) = x 2 + y 2 + z 2. Although we cannot plot the graph of this function, we can graph some of its level surfaces. The equation for a level surface, x2 +y2 +z2 = c x 2 + y 2 + z 2 = c, is the equation for a sphere of radius c√ c. The applet did not load, and the above is only a static image ...
For a function of three variables, a level set is a surface in three-dimensional space that we will call a level surface. For a constant value c c in the range of f(x, y, z) f (x, y, z), the level surface of f f is the implicit surface given by the graph of c = f(x, y, z) c = f (x, y, z).
Dec 29, 2020 · Note how the \(y\)-axis is pointing away from the viewer to more closely resemble the orientation of the level curves in (a). Figure \(\PageIndex{5}\): Graphing the level curves in Example 12.1.4. Seeing the level curves helps us understand the graph. For instance, the graph does not make it clear that one can "walk'' along the line \(y=-x ...

What is a level curve?
By fixing some value for z z and varying all possible x x and y y, we would get a level curve of z = f(x, y) z = f (x, y). By changing values for z z, one can get different level curves. For z = x2 +y2− −−−−−√ z = x 2 + y 2, the level curves would be concentric circles. My question is, What do level curves signify?
