One way to collapse the graph of a scalarvalued function of two variables into a twodimensional plot is through level curves 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 Describe in words the level curves of the paraboloid z = x2 y2 Choose the correct answer below A The level curves are parabolas of the form x2 = zo B The level curves are lines of the form x y = C The level curves are parabolas of the form y2 = zo D The level curves are circles of the form x2 y2 = 2oGraphs of functions and level curves The elliptic parabolloid z = x2 y2 ParametricPlot3D@8Sqrt@tD Cos@uD, Sqrt@tD Sin@uD,t
The animation below shows the paraboloid \(z=x^2y^2\) with \(\vec r(t) = \langle t, t, 2t^2\) tracing out its intersection with the plane \(y=x\) Further Questions Find a parameterization of the curve in the example that traces out the curve half as fastThere would be an in–nite number of intersecting lines (level curves/contours) (a) Consider the upper hemisphere z= p 1 x2 y2 What would be the level curve/contour for z= k= 1?Each one is an ellipse whose major axis coincides with the x axis Hence, the horizontal vector Vw = (2x 0, 0) will be normal to the level curve at the point (x 0, 0)
Level curves and surfaces The level curves of are curves in the plane along which has a constant value We will sketch level curves corresponding to a couples values, such as The level set is given by , or This is a parabola in as a function of Now we add the and level sets Solving for level curves of an elliptic paraboloid given by quadric surface equation Follow 18 views (last 30 days) Show older comments supernoob on 16 Jul (level curve) at a given height z, and to get the vertices of this ellipse It would be nice to plot the ellipse, too I have to do this over and over again, so the fastest way wouldSo consider for a paraboloid graph, whose level curves are circles, the gradient points radially outward from the origin The relationship between the two is shown in the next graph As the gradient, whose form for a paraboloid with a circular crosssection is 〈 〉, get closer to the origin they get shorter, and further

Level Curves of a Paraboloid This example requires WebGL Visit getwebglorg for more info When we lift the level curves up onto the graph, we get "horizontal traces"Question 1327 Describe in words the level curves of the paraboloid z=x y2 Choose the correct answer below A The level curves are lines of the form x y=Zo O B The level curves are circles of the form x2 y2 ° C The level curves are parabolas of the form x2Zo 0 DAccording to the internet, finding the circumference of paraboloid level curves seemed a tad too easy It said to simply plug in the z value or the height level into the formula c = x^2 y^2 or something like that, square root the c value to get the level curve circles radius For example at z = 1 the circles radius would be square root 1 aka 1

This is an elliptic paraboloid and is an example of a quadric surface We saw several of these in the previous section The next topic that we should look at is that of level curves or contour curves 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 anyFor this question They give us the privilege 16 minus X squared over four minus y squared over 16 And they wanted to show that a tangent lines the level care but see 16 minus X squared over four minus y squared over 16 is equal to quote So this is our love worker They want us to show at the given point The slope at this point is equal to the radium Describe the level curves of the function z = 2x2 y2 1 for c = 0,2,3 Answer Ellipses 2 Sketch several level curves for the paraboloid z = 4 x2 y2 3 Describe the level surfaces of the function F(x, y, z) = 9 x2 y2 – 22 Answer Level surfaces are spheres x2 y2 z2 = p2 (0
