That is, the integral of a vector field \(\mathbf F\) over a surface \(S\) depends on the orientation of \(S\) but is otherwise independent of the parametrization. In fact, changing the orientation of a surface (which amounts to multiplying the unit normal \(\mathbf n\) by \(-1\), changes the sign of the surface integral of a vector field.

We will also see how the parameterization of a surface can be used to find a normal vector for the surface (which will be very useful in a couple of sections) and how the parameterization can be used to find the surface area of a surface.

Surface divided into small patches by a parameterization of the surface. A double integral over the surface of a sphere might have the circle through it.

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.

Back to …We defined, in §3.3, two types of integrals over surfaces. We have seen, in §3.3.4, some applications that lead to integrals of the type ∬SρdS. We now look at one application that leads to integrals of the type ∬S ⇀ F ⋅ ˆndS. Recall that integrals of this type are called flux integrals. Imagine a fluid with.The vector line integral introduction explains how the line integral $\dlint$ of a vector field $\dlvf$ over an oriented curve $\dlc$ “adds up” the component of the vector field that is tangent to the curve. In this sense, the line integral measures how much the vector field is aligned with the curve. If the curve $\dlc$ is a closed curve, then the line integral …Total flux = Integral( Vector Field Strength dot dS ) And finally, we convert to the stuffy equation you’ll see in your textbook, where F is our field, S is a unit of area and n is the normal vector of the surface: Time for one last detail — how do we find the normal vector for our surface?

The amount of the fluid flowing through the …AJ B. 8 years ago. 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.
