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.
15.5.4 The Gradient and Level Curves. Theorem 15.11 states that in any direction orthogonal to the gradient. ∇f(a,b) , the function. f. does not change at. (a,b) Recall from Section 15.1 that the curve. f(x,y)=.
Mar 2, 2022 · Let us use the function $f(x,y)=x^3+5 x^2+x y^2-5 y^2$ and check wether it has critical points using level curves. In the first step, let us draw the level curves (blue) and the derivatives $\frac{\partial f}{\partial x}$ and $\frac{\partial f}{\partial y}$ (green).
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.
Interpreting level curves for functions of two variables. Level curves can indicate the shape and behavior of the function, such as whether it is increasing or decreasing. The arrangement of level curves can reveal local maxima, minima, and saddle points.

For $c=1$, the level curve is $x^2-y^2=1$, which is a hyperbola passing vertically through the $x$-axis at the points $(\pm 1,0)$. For $c=2$, the level curve is $\left(\frac{x}{\sqrt{2}}\right)^2-\left(\frac{y}{\sqrt{2}}\right)^2=1$, which is a hyperbola passing vertically through the $x$-axis at the points $(\pm \sqrt{2},0)$.
