Use Stokes' theorem to compute ∫∫ScurlF · dS, where F(x, y, z) = 〈1, xy2, xy2 〉 and S is the part of the plane y + z = 2 inside the cylinder x2 + y2 = 1. Stokes' Dec 8, 2016 Solution: This question uses Stokes' theorem: S is a surface with boundary, and we are taking Solution: This problem uses Green's theorem. Differentiability, Rolle's Theorem.

## 2018-06-04 · Here is a set of practice problems to accompany the Green's Theorem section of the Line Integrals chapter of the notes for Paul Dawkins Calculus III course at Lamar University.

Solution. If we want to use Stokes’ Theorem, we will need to nd @S, that is, the boundary of S. Similarly, if F is a vector field such that curl F. n = 1 on a surface S with boundary curve C, then Stokes' Theorem says that computes the surface area of S. Problem 5: Let S be the spherical cap x 2 + y 2 + z 2 = 1, with z >= 1/2, so that the bounding curve of S is the circle x 2 + y 2 = 3/4, z=1/2. (Or is Stokes’ theorem not applicable in this case?) Given a surface, boundary curve, and 3D vector field, convert between surface integrals and line integrals using Stokes’ theorem.

Solution.

The class will be discussed in Hindi and notes will be provided in English. Sketch of proof. Some ideas in the proof of Stokes’ Theorem are: As in the proof of Green’s Theorem and the Divergence Theorem, first prove it for \(S\) of a simple form, and then prove it for more general \(S\) by dividing it into pieces of the simple form, applying the theorem on each such piece, and adding up the results.

Stokes's Theorem is kind of like Green's Theorem, whereby we can evaluate some multiple integral rather than a tricky line integral.

### Section 8.2 - Stokes’ Theorem Problem 1. Use Stokes’ Theorem to evaluate ZZ S curl (F) dS where F = (z2; 3xy;x 3y) and Sis the the part of z= 5 x2 y2 above the plane z= 1. Assume that Sis oriented upwards. Solution. If we want to use Stokes’ Theorem, we will need to nd @S, that is, the boundary of S.

Let Cbe any closed curve and let Sbe any surface bounding C. Let F~ be a vector eld on S. I C F~d~r= ZZ S (r F~) n^ dS: So disagree that Stokes' theorem (however capitalised) is in any way ambiguous of interpretation. It is Stokes's theorem that is (however slightly) ambiguous of interpretation. Andrewa 20:53, 18 December 2018 (UTC) Andrewa, I get where you are going, but I can't say I agree with your line of reasoning. I've rewritten Stokes's theorem right over here what I want to focus on in this video is the question of orientation because there are two different orientations for our boundary curve we could go in that direction like that or we could go in the opposite direction we could be going like that and there are also two different orientations for this normal vector the normal vector might pop out PDF | Surface Integrals, Generalized Stokes’Theorem, Modern form of Stokes’Theorem, Remarks on Stokes’Theorem, Some Practical Examples, Practice Problem 1.

### In short, Stokes's theorem allows the transformation $$\left\{\text{flux integral of the curl}\right\}\leftrightarrow\left\{\text{line integral of the vector field}\right\}$$ So you should only reach for this theorem if you want to transform the flux integral of a curl into a line integral.
