WebIf F(x, y) = 〈P, Q〉 = 〈− y 2, x 2〉, then Qx − Py = 1. Therefore, by the same logic as in Example 6.40, area ofD = ∬DdA = 1 2∮C−ydx + xdy. (6.14) It’s worth noting that if F = 〈P, Q〉 is any vector field with Qx − Py = 1, then the logic of the previous paragraph works. So. WebIn exercises requiring estimations or approximations, your answers may vary slightly from the answers given here. 1. (a) The point (−1, −2) is on the graph of f , so f (−1) = −2. (b) When x = 2, y is about 2.8, so f (2) ≈ 2.8. (c) f (x) = 2 is equivalent to y = 2. When y = 2, we have x = −3 and x = 1.

WebUse Fubini’s theorem to compute the double integral ∬ R f(x, y)dA where f(x, y) = x and R = [0, 2] × [0, 1]. The double integration in this example is simple enough to use Fubini’s theorem directly, allowing us to convert a double integral into an iterated integral.
