Level Curves and Surfaces The graph of a function of two variables is a surface in space Pieces of graphs can be plotted with Maple using the command plot3dFor example, to plot the portion of the graph of the function f(x,y)=x 2 y 2 corresponding to x between 2 and 2 and y between 2 and 2, type > with (plots);LEVEL CURVES The level curves (or contour lines) of a surface are paths along which the values of z = f(x,y) are constant;In your last example, if $z$ is constant then so is $x^2y^2$ This should look familiar, as the level curves for that are hyperbolas If you want to improve, first get comfortable with the conic sections (points, lines, double lines, circles, ellipses, parabolas, and hyperbolas) You could then move on to more complicated ones

Other examples of level curves are isobars and isotherms An isobar is a planar curve where the atmospheric pressure is constant An isotherm is a planar curve along which the temperature is constant De nition 3 (Potential) The function U(x;y) in a conservation law is called a potential The dynamical equation is the rst order di erential equationLevel Curves Author Kristen Beck Topic Functions This worksheet illustrates the level curves of a function of two variables You may enter any function which is a polynomial in both andLevel Curves and Surfaces Example 2 In mathematics, a level set of a function f is a set of points whose images under f form a level surface, ie a surface such that every tangent plane to the surface at a point of the set is parallel to the level set
3月 05, 21 Level Surfaces Given w = f(x,y,z) then a level surface is obtained by considering w = c = f(x,y,z) The interpretation being that on a level surface f has the same value at every pt For example f could represent the temperature at1 Consider the function f ( z) = z 2 Prove that level curves of R e ( f ( z)) and I m ( f ( z)) at z = 1 2 i are orthogonal to each other I am not sure how to apply level curves or contour lines for complex variables As far as real variables go, I am aware that for a function like f ( x, y) = x 2 y 2, the level curves are the circlesLevel Curves and Surfaces Example 1 In mathematics, a level set of a function f is a set of points whose images under f form a level surface, ie a surface such that every tangent plane to the surface at a point of the set is parallel to the level set

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 Example To illustrate this we first draw the graph of z = x2 y2 On this graph we draw contours, which are curves at a fixed height z = constant For example the curve at height z = 1 is the circle x2 y2 = 1 On the graph 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)Ie the level curves of a function are simply the traces of that function in various planes z = a, projected onto the xy plane The example shown below is the surface Examine the level curves of the function Sliding the slider will vary a from a = 1 to a = 1

Level Curves One common example of level curves occurs in topographic maps of mountainous regions, such as the map in Figure 12 Figure 12 22 Level Curves The level curves are curves of constant elevation above sea level If you walk along one of these contour lines, you neither ascend nor descend Another common example is the temperature function introduced in the openingString defining the captions for each axis with @ as a field separator, for example "X@Y@Z" flag a real vector of size three flag=mode,type,box mode string representation mode mode=0 the level curves are drawn on the surface defined by (x,y,z) mode=1 the level curves are drawn on a 3D plot and on the plan defined by the equation z=zlev mode=2 the level curves are drawn onFor example, "largest * in the world" Search within a range of numbers Put between two numbers For example, camera $50$100
