Level Curve | Introduction to Level Curve.
Set of all points in plane,where the function f(x,y) has constant value.
One of the most useful and common methods for visualizing functions (or surfaces) of two varibles is a Contour Map in which points of constant elevation are joined in a 2D plane to form level curves (or contour curves).
The set of points in the domain of a function where the function is constant. The nice part of of level sets is that they live in the same dimensions as the domain of the function. A level set of a function of two variables
f(x,y) is a curve in the two-dimensional xy-plane, called a level curve.
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)f(x,y) is the curve of points (x,y)(x,y) where f(x,y)f(x,y) is some constant value. A level curve is simply a cross section of the graph of z=f(x,y)z=f(x,y) taken at a constant value, say z=cz=c. A function has many level curves, as one obtains a different level curve for each value of cc in the range of f(x,y)f(x,y). We can plot the level curves for a bunch of different constants cc together in a level curve plot, which is sometimes called a contour plot.
