You can infer all sorts of data from level curves, depending on your function. The spacing between level curves is a good way to estimate gradients: level curves that are close together represent areas of steeper descent/ascent.
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.

Unit #19 : Level Curves, Partial Derivatives Goals: • To learn how to use and interpret contour diagrams as a way of visualizing functions of two variables. • To study linear functions of two variables. • To introduce the partial derivative. Reading: Sections 12.3,12.4,14.1 and 14.2.
Sep 29, 2023 · A level curve of a function \(f\) of two independent variables \(x\) and \(y\) is a curve of the form \(k = f(x,y)\text{,}\) where \(k\) is a constant. A level curve describes the set of inputs that lead to a specific output of the function.
Level curves help visualize how a function behaves over its domain by representing points with equal output values. In two-variable functions, level curves can be used to identify contours that separate regions of different values, providing insight into function behavior.
