Definition. 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.
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 \(f\left( {x,y} \right) = k\).
Nov 26, 2019 · Find a curve on $xy$-plane which passes through $(1, 1)$ and intersects all level curves of the function $f(x, y) = x^2e^y$ orthogonally.
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 $(\pm 1,0)$.
