# Stokes theorem

The next question is what the microscopic circulation along a surface should be. Similarly, for a surface, we will want the microscopic circulation along the surace. This corresponds to the component of the curl that is perpendicular to the surface, i. You can see this using the right-hand rule. Stokes' Theorem relates line integrals of vector fields to surface integrals of vector fields. Let n denote the unit normal vector to S with positive z component.

Let C denote this circle traversed in the counter clockwise direction.

Section Stokes' Theorem. In this section we are going to take a look at a theorem that is a higher dimensional version of Green’s grupobittia.com Green’s Theorem we related a line integral to a double integral over some region. In this section we define absolute (or global) minimum and maximum values of a function and relative (or local) minimum and maximum values of a function. It is important to understand the difference between the two types of minimum/maximum (collectively called extrema) values for many of the applications in this chapter and so we use a variety of examples to help with this. Section Stokes' Theorem. In this section we are going to take a look at a theorem that is a higher dimensional version of Green’s Theorem. In Green’s Theorem we related a line integral to a double integral over some region. In this section we are going to relate a line integral to a surface integral.

If F is a vector field with continuous partial derivatives in some region containing S, then Stokes' Theorem states In general C is the boundary of S and is assumed to be piecewise smooth. For the above equality to hold the direction of the normal vector n and the direction in which C is traversed must be consistent.

Suppose that n points in some direction and consider a person walking on the curve C with their head pointing in the same direction as n. For consistency C must be traversed in such a way so that the surface is always on the left.

## Stokes' Theorem

Let us first compute the line integral. The line integral is given by Now, let us compute the surface integral. The expression on the right is a double integral.

It is convenient to convert to polar coordinates to compute the double integral. The double integral becomes The inner integral is The final result for the inner integral is The outer integral is.Stokes's law: Stokes’s law,, mathematical equation that expresses the settling velocities of small spherical particles in a fluid medium.

The law, first set forth by the British scientist Sir George G. Stokes in , is derived by consideration of the forces acting on a particular particle as it sinks through a. Using Green's Theorem to solve a line integral of a vector field. Stokes' theorem is a generalization of Green’s theorem to higher dimensions. While Green's theorem equates a two-dimensional area integral with a corresponding line integral, Stokes' theorem takes an integral over an.

Feb 15,  · A generalized version of Stokes' theorem, which includes the original Stokes theorem, Green's theorem and the fundamental theorem of calculus as special cases and is applicable in all dimensions, uses integration of differential forms.

The term refers, in the modern literature, to the following theorem. The theorem can be considered as a generalization of the Fundamental theorem of calculus.

The classical Gauss-Green theorem and the "classical" Stokes formula can be recovered as particular cases. The latter is also often called. Advanced Calculus: Differential Calculus and Stokes' Theorem (De Gruyter Textbook) - Kindle edition by Pietro-Luciano Buono.
