Setting z = k z = k
- The next topic that we should look at is that of level curves or contour curves. 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.

Level curves of the function g(x,y)=√9−x2−y2 g (x y) = 9 − x 2 − y 2, using c=0,1,2 c = 0 1, 2, and 3 3 (c=3 c = 3 corresponds to the origin). A graph of the various level curves of a function is called a contour map. Example: Making a Contour Map.

A function has many level curves, as one obtains a different level curve for each value of $c$ in the range of $f(x,y)$. We can plot the level curves for a bunch of different constants $c$ together in a level curve plot, which is sometimes called a contour plot.
Given a function f (x, y) f (x, y) and a number c c in the range of f, a 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.

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.
