- 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. Returning to the function g(x, y) = √9−x2 −y2 g (x, y) = 9 − x 2 − y 2, we can determine the level curves of this function.

Aug 17, 2024 · Use the gradient to find the tangent to a level curve of a given function. Calculate directional derivatives and gradients in three dimensions.
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 $z=c$.

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.
