- 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.
Given a function [latex]f\,(x,\ y)[/latex] and a number [latex]c[/latex] in the range of [latex]f[/latex], a level curve of a function of two variables for the value [latex]c[/latex] is defined to be the set of points satisfying the equation [latex]f\,(x,\ y)=c[/latex].
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 \(f\left( {x,y} \right) = k\).

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.
Recall from Section 15.1 that the curve. f(x,y)=. z. 0. , where. z. 0. is a constant, is a level curve, on which function values are constant. Combining these two observations, we conclude that the gradient.

Recall that the level curves of a function \(f(x, y)\) are the curves given by \(f(x, y) =\) constant. Recall also that the gradient \(\nabla f\) is orthogonal to the level curves of \(f\)
