39 a contour diagram for a function f(x,y) is shown below.

Contour diagrams give us the same kind of information about a function. Below is a contour diagram of the same surface shown in above. The level curves are graphs in the x y -plane of curves f ( x, y) = c for various constants c. Each of the squares corresponds to one of the bumps on the surface. [In other words, the values of f(x,y) do not change when y changes, so f(x,y) can be viewed as a function of x alone, which makes f y(x,y) = 0 everywhere.] (c) We already know that f x is everywhere positive, or in other words that f(x,y) increases as x increases with y held constant. Moreover, the spacing of the contours tells us that as x ...

In Problems 2-6, sketch a contour diagram for the function with at least four labeled contours. Describe in words the contours and how they are spaced. 2. f(x;y) = x+ y If we set f(x;y) = c, the contours will satisfy y= c x, or straight lines with slope -1. 3. f(x;y) = 3x+ 3y If we set f(x;y) = c, the contours will satisfy 3y = c 3x, or y= c 3 ... A contour map for a function fis given. Use it to estimate f x(2;1) and f y(2;1). Solution: We can estimate f x by observing that as xgoes from 1.5 to 2.5, with y= 1 xed, f seems to go from about 9 to 12. Therefore f x(2;1) is approximately 3. As ygoes from 0.5 to 1.5, with x= 2 xed, fgoes from about 11 to about 9, so f y(2;1) is roughly -2. 2. Stewart 14.3.70 Ask about how fx changes in the y-direction and about fy. 6.

A contour map for a function fis given. Use it to estimate f x(2;1) and f y(2;1). Solution: We can estimate f x by observing that as xgoes from 1.5 to 2.5, with y= 1 xed, f seems to go from about 9 to 12. Therefore f x(2;1) is approximately 3. As ygoes from 0.5 to 1.5, with x= 2 xed, fgoes from about 11 to about 9, so f y(2;1) is roughly -2. 2. Stewart 14.3.70
