The whole point here is to give you the intuition of what a surface integral is all about. So we can write that d sigma is equal to the cross product of the orange vector and the white vector. The orange vector is this, but we could also write it like this. This was the result from the last video.3.3: Surface Integrals. Page ID. Joel Feldman, Andrew Rechnitzer and Elyse Yeager.

In this sense, surface integrals expand on our study of line integrals. Just as with line integrals, there are two kinds of surface integrals: a surface integral of a scalar-valued function and a surface integral of a vector field. The Divergence Theorem.

The flow rate of the fluid across S is ∬ S v · d S. ∬ S v · d S. Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube.A surface integral over a vector field is also called a flux integral. Just as with vector line integrals, surface integral \(\displaystyle \iint_S \vecs F \cdot \vecs N\, dS\) is easier to compute after surface \(S\) has been parameterized.

Yes, as he explained explained earlier in the intro to surface integral video, when you do coordinate substitution for dS then the Jacobian is the cross-product of the two differential vectors r_u and r_v. The intuition for this is that the magnitude of the cross product of the vectors is the area of a parallelogram. Surface integrals are kind of like higher-dimensional line inte Stokes’ theorem relates a vector surface integral over surface \(S\) in space to a line integral around the boundary of \(S\). Therefore, just as the theorems before it, Stokes’ theorem can be used to reduce an integral over a geometric object \(S\) to an integral over the boundary of \(S\).A volume integral is the calculation of the volume of a three-dimensional object. The symbol for a volume integral is “∫”. Just like with line and surface integrals, we need to know the equation of the object and the starting point to calculate its volume.
