The use of contour lines to help understand a function whose domain is part of the plane goes back to the year 1774 A group of surveyors had collected a large number of the elevations of points on Mount Schiehalli in Scotland They were doing this in order to estimate its mass and by its gravitational attraction, the mass of the earth They asked the mathematician Charles Hutton forSee Answer Check out a sample Q&A here Want to see this answer and more?CONTOUR MAPS LOREN SPICE In class, we discussed the fact that a contour map for a function z = f(x;y) of two variables is a picture of what you would see if you looked down on the graph from very high up on the zaxis We assume that you're so high up that you can't tell the actual height (ie, the actual zvalues) of any of the points, but that you can tell when two points have the

Contour maps give a way to represent the function while only drawing on the twodimensional input space Step 1 Start with the graph of the function Example function graph Step 2 Slice the graph with a few evenlyspaced level planes, each of which should be parallel to the planeContour Maps Simple contour plotting Example import matplotlibpyplot as plt import numpy as np # generate 101 x and y values between 10 and 10 x = nplinspace(10, 10, 101) y = nplinspace(10, 10, 101) # make X and Y matrices representing x and y values of 2d plane X, Y = npmeshgrid(x, y) # compute z value of a point as a function of x and y (z = l2 distance form 0,0) Z = npsqrt(X **CONTOUR MAP Drawing several contour curves ff(x;y) = cg or several contour surfaces ff(x;y;z) = cg produces a contour map The example shows the graph of the function f(x;y) = sin(xy) We draw the contour map of f The curve sin(xy) = cis xy= C, where C= arcsin(c) is a constant The curves y= C=xare hyperbolas except for C= 0, where y= 0 is a line Also the line x= 0 is a contour
