Level Curves

These level curves will be concentric circles with center $(0, 0)$ The image below depicts the level curve of this paraboloid corresponding to $z = 2$ Another example is the two variable realvalued function $f(x, y) = x^2 y^2$which represents a hyperboloid The level curves generated by the planes $z = 1$, $z = 2$, and $z = 3$are hyperbolasEvaluations of Curves London To evaluate this company please Login or Register Statistics 37 times viewed 410 times listed

Level curves matlab-PAG 112 pH – Titration Curves Titration or pH curves are obtained by reacting known concentrations of acid with alkalis and measuring the pH during the neutralisation The more data points that are available;Solution First, let z be equal to k, to get f (x,y) = k Secondly, we get the level curves, or Notice that for k >0 describes a family of ellipses with semiaxes and Finally, by variating the values of k, we get graph bellow (Figure 3), called, level curves or contour map Firgure 3 Level curves of f

Figure 433 Sea level curve for the last 24,000 years These data are a compiled dataset from a number of different regions and from a number of different proxies As shown, sea levels were at their lowest point between 22 and 18,000 years ago, and rose steadily and sharply from about 15,000 years ago to around 8,000 years ago when they approached a more modernTitration Curves Titration or pH curves are obtained by reacting known concentrations of acid with alkalis and measuring the pH during the neutralisation If is it working correctly it should read 90 5cm 3 at time is added to the beaker and the pH measured after each addition, until a total of 50 cm 3 has been added 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)

Level curves and contour plots are another way of visualizing functions of two variables If you have seen a topographic map then you have seen a contour plot On this graph we draw contours, which are curves at a fixed height z = constant For example the curve atThey are used to create threedimensional surfaces from twodimensional contours For example, the following image shows several level curves and what these curves look like when they areYou have a function f R 2 → R The level curves of f is the set { ( x, y) ∈ R 2 f ( x, y) = K, K ∈ R } So, in order to find the level curves of your function, just set it equal to a constant K, and try different values of K For instance f ( x, y) = ( x 2 y 2 − 1) ( 2 x y − 1) = K Now, test values foe K, say K = − 1, −

The level curves of are curves in the plane along which has a constant value The level surfaces of are surfaces in space on which has a constant value Sometimes, level curves or surfaces are referred to as level sets Practice problems Sketch the level curves of Solution Sketch the threedimensional surface and level curves of Solution Definition The level curves of a function f of two variables are the curves with equations f (x,y) = k, where k is a constant (in the range of f) A level curve f (x,y) = k is the set of all points in the domain of f at which f takes on a given value k In other words, it shows where the graph of f has height k
