The curl is a form of differentiation for vector fields. The corresponding form of the fundamental theorem of calculus is Stokes' theorem, which relates the surface integral of the curl of a vector field to the line integral of the vector field around the boundary curve. The notation curl F is more common in North America.Theorem 1 (Stokes' Theorem) Assume that S is a piecewise smooth surface in R3 with boundary ∂S as described above, that S is oriented the unit normal n and that ∂S has the compatible (Stokes) orientation. Assume also that F is any vector field that is C1 in an open set containing S. Then ∬ScurlF ⋅ ndA = ∫∂SF ⋅ dx.Courses on Khan Academy are always 100% free.

Green’s theorem relates the integral over a connected region to an integral over the boundary of the region. Green’s theorem is a version of the Fundamental Theorem of Calculus in one higher dimension. Green’s Theorem comes in two forms: a circulation form and a flux form. In the circulation form, the integrand is \(\vecs F·\vecs T\).

An amazing consequence of Stokes’ theorem is that if S′ is any other smooth surface with boundary C and the same orientation as S, then \[\iint_S curl \, F \cdot dS = \int_C F \cdot dr = 0\] because Stokes’ theorem says the surface integral depends on the line integral around the boundary only.One important subtlety of Stokes' theorem is orientation. We need to be careful about orientating the surface (which is specified by the normal vector n n) properly with respect to the orientation of the boundary (which is specified by the tangent vector). Remember, changing the orientation of the surface changes the sign of the surface integral.May 4, 2023 · Stokes theorem is used for the interpretation of curl of a vector field. Water turbines and cyclones may be an example of Stokes and Green’s theorem. This theorem is a very important tool with Gauss’ theorem in order to work with different sorts of line integrals and surface integrals under definite integrals . 3) Stokes theorem was found by Andr´e Amp`ere (1775-1836) in 1825 and rediscovered by George Stokes (1819-1903). 4) The flux of the curl of a vector field does not depend on the surface S, only on the boundary of S. 5) The flux of the curl through a closed surface like the sphere is zero: the boundary of such a surface is empty. Example.Stokes' theorem says that ∮C ⇀ F ⋅ d ⇀ r = ∬S ⇀ ∇ × ⇀ F ⋅ ˆn dS for any (suitably oriented) surface whose boundary is C. So if S1 and S2 are two different (suitably oriented) surfaces having the same boundary curve C, then. ∬S1 ⇀ ∇ × ⇀ F ⋅ ˆn dS = ∬S2 ⇀ ∇ × ⇀ F ⋅ ˆn dS. For example, if C is the unit ...
