In mathematics, a level set of a real-valued function f of n real variables is a set of the form Lc(f)={(x₁,⋯,xₙ) ∣ f(x₁,⋯,xₙ)=c} , that is, a set where the function takes on a given constant value c. When the number of variables is two, a level set is generically a curve, called a level curve, contour line, or isoline. So a level curve is the set of all real-valued solutions of an equation in two variables x₁ and x₂.
