Stokes' theorem, also known as Kelvin–Stokes theorem after Lord Kelvin and George Stokes, the fundamental theorem for curls or simply the curl theorem, is a theorem in vector calculus on . Given a vector field , the theorem relates the integral of the curl of the vector field over some surface, to the line integral of the vector field around the boundary of the surface. To use Stokes’ Theorem, we need to rst nd the boundary Cof Sand gure out how it should be oriented. The boundary is where x2+ y2+ z2= 25 and z= 4. Substituting z= 4 into the rst equation, we can also describe the boundary as where x2+ y2= 9 and z= 4.

A theorem proposing that the surface integral of the curl of a function over any surface bounded by a closed path is equal to the line integral of a particular vector function round that path. ‘Perhaps the most famous example of this is Stokes' theorem in vector calculus, which allows us to convert line integrals into surface integrals and vice versa.’ theorem on a rectangle to those of Stokes’ theorem on a manifold, elementary and sophisticated alike, require that ω ∈ C1.

F(x,y,z)=xy i + 3zj+5yk, C is the curve of intersection of the plane x+z=10 and the cylinder x^2+y^2=9. In practice, we use Stokes’ theorem in pretty much all of the same cases that we use Green’s theorem: Turning integrals of functions over really awful curves into integrals of curls of func-tions over surfaces.

Be able to use Stokes's Theorem to compute line integrals. In this section we will generalize Green's theorem to surfaces in R3. Let's start with a definition.

Stokes' theorem generalizes Green's the oxeu inn the plane. Now, we compute the same integral, but by using We use Stokes theorem one more time you.

You get a surface which is cylinder like and has two boundaries (both circles). But they are oriented di erently. where S is a surface whose boundary is C. Using Stokes’ Theorem on the left hand side of (13), we obtain Z Z S {curl B−µ0j}·dS= 0 Since this is true for arbitrary S, by shrinking C to smaller and smaller loop around a ﬁxed point and dividing by the area of S, we obtain in a manner that should be familiar by now: n·{curl B− µ0j} = 0.
