- The level curves of a function z = (x, y) are curves in the x y -plane on which the function has the same value, i.e. on which, z = k, where k is some constant.
Level curves of the function g(x,y)=√9−x2−y2 g (x y) = 9 − x 2 − y 2, using c=0,1,2 c = 0 1, 2, and 3 3 (c=3 c = 3 corresponds to the origin). A graph of the various level curves of a function is called a contour map.
Functions of two variables have level curves, which are shown as curves in the x y-plane. x y-plane. However, when the function has three variables, the curves become surfaces, so we can define level surfaces for functions of three variables.
Nov 16, 2022 · The level curves of the function \(z = f\left( {x,y} \right)\) are two dimensional curves we get by setting \(z = k\), where \(k\) is any number. So the equations of the level curves are \(f\left( {x,y} \right) = k\).
Level curves are used to visualize functions of two variables, providing insight into how the function's value changes with varying inputs. The intersection of level curves can indicate critical points where the function may have local maxima, minima, or saddle points.
The level curves of a function \(z=(x,y)\) are curves in the \(xy\)-plane on which the function has the same value, i.e. on which \(z=k\text{,}\) where \(k\) is some constant. Note: Each point in the domain of the function lies on exactly one level curve.
Level curves allow us to visualize where a multivariable function takes on constant values, helping to identify regions where the function increases or decreases. By analyzing these curves, we can determine where critical points occur—where the gradient is zero.

What are contour lines & level curves?
Level curves, also known as contour lines, are two-dimensional curves that represent the set of points in a function of two variables where the function has a constant value. They are used to visualize the behavior of a function over a region in the xy-plane.
