If z x3 + 2x2y + 9y2 find zx and zy
WebIt easy to see that this theorem follows from what we already know about functions of one variable. Suppose that f(x,y) has a local maximum or minimum at (a,b). Define the single variable functions F(x) = f(x,b) G(y) = f(a,y) Then a is a local maximum or minimum for the function F(x), so that F′(a) = 0, and b is WebThe flow rate of the fluid across S is ∬ S v · d S. ∬ S v · d S. Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube.
