WebNov 16, 2024 · A good example of a closed surface is the surface of a sphere. We say that the closed surface \(S\) has a positive orientation if we choose the set of unit normal vectors that point outward from the region \(E\) while the negative orientation will be the set of unit normal vectors that point in towards the region \(E\). WebSection 6.4 Exercises. For the following exercises, evaluate the line integrals by applying Green’s theorem. 146. ∫ C 2 x y d x + ( x + y) d y, where C is the path from (0, 0) to (1, 1) along the graph of y = x 3 and from (1, 1) to (0, 0) along the graph of y = x oriented in the counterclockwise direction. 147.

WebFeb 5, 2016 · For Green's theorem, this page has a good explanation of the technique and a good way to think about the multiple boundaries. And this page goes into more detail about why the technique works. The orientation of the curves is positive if the region is always to the left of the curve in the direction of travel, and you sum the positive line ... WebStep 1 Since C follows the arc of the curve y = sin x from (0,0) to (1,0), and the line segment y = 0 from (TT, 0) to (0, 0), then C has a negative negative orientation. Step 2 Since C …

WebNov 16, 2024 · This, in turn, means that we can’t actually use Green’s Theorem to evaluate the given integral.
