The level curves of the function \(z = f\left( {x,y} \right)\) are two dimensional curves we get by setting \(z = k\), where \(k\) is any number So the equations of the level curves are \(f\left( {x,y} \right) = k\)Free online 3D grapher from GeoGebra graph 3D functions, plot surfaces, construct solids and much more!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 $z=c$ 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

Visualizing level curves This allows students to see level curves drawn simultaneously with the 3D image of the intersection of the plane and the curve The only issue the user should be aware of is that the 2variable function must be polynomial in both x and y2 Answers2 Active Oldest Votes 1 In your first example, the proper solution is y = ± k − x 2 You left out the plusorminus That is not a small thing there are usually two values of y for each x, and that greatly affects the plotting of the curves I would say that there is no single general method for finding level curves, in a The level curves of f(x,y) = x 2y 2 are hyperbolas Here they are shown at the appropriate heights Example 7 The level curves of f(x,y)=2e(x1) 2y 2 3e(x2) 2(y1) 22e(x1) 2(y2) 2 are shown below Comparing with the graph in Example 4, we see that the points (x,y) at which f has maxima and minima are at the centers of circular level curves

For each $c$, this is a line with slope $A/B$ and $y$intercept $y = (DCc)/B$ Since the slope does not depend on $c$, the level curves are parallel lines, and as $c$ runs over equally spaced values these lines will be a constant distance apart Consequently, the contour map of a plane consists of equally spaced parallel linesA collection of level curves of f is shown in the following figure The number on each curve is the value of the function to which it corresponds The circles are closer together for larger values of the function, so that the graph of the function is a bowl with sides whose slopes increase as we move away from the centerLevel Curves Level curves are slices through a surface When we have a surface z = f(x,y) z = f ( x, y) , level curves are horizontal slices of constant z z , ie they look like f(x,y) = k f ( x
