- 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.

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. A level curve is simply a cross section of the graph of $z=f(x,y)$ taken at a constant value, say $z=c$. A ...
Nov 16, 2022 · The next topic that we should look at is that of level curves or contour curves. 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.
Recall that the level curves of a function f(x, y) f (x, y) are the curves given by f(x, y) = f (x, y) = constant. Recall also that the gradient ∇f ∇ f is orthogonal to the level curves of f f.
The level curves are given by $x^2-y^2=c$. For $c=0$, we have $x^2=y^2$; that is, $y=\pm x$, two straight lines through the origin. For $c=1$, the level curve is $x^2-y^2=1$, which is a hyperbola passing vertically through the $x$-axis at the points $(\pm 1,0)$.

Dec 29, 2020 · Given a function \(z=f(x,y)\), we can draw a "topographical map'' of \(f\) by drawing level curves (or, contour lines). A level curve at \(z=c\) is a curve in the \(x\)-\(y\) plane such that for all points \((x,y)\) on the curve, \(f(x,y) = c\).
