**Introduction to a line integral of a vector field Math ...**

A line integral (sometimes called a path integral) is the integral of some function along a curve. One can integrate a scalar valued function along a curve, obtaining for example, the mass of a wire from its density.**Calculus III Line Integrals of Vector Fields**

In this section we will define the third type of line integrals we’ll be looking at : line integrals of vector fields. We will also see that this particular kind of line integral is related to special cases of the line integrals with respect to x, y and z.**Vector line integral examples Math Insight**

Example 1. If a force is given by \begin{align*} \dlvf(x,y) = (0,x), \end{align*} compute the work done by the force field on a particle that moves along the curve $\dlc$ that is the counterclockwise quarter unit circle in the first quadrant.**Line Integrals of Vector Fields Math24**

Line Integrals of Vector Fields Definition Suppose that a curve \(C\) is defined by the vector function \(\mathbf{r} = \mathbf{r}\left( s \right),\) \(0 \le s \le S,\) where \(s\) is the arc length of the curve.**Line integral **

The line integral of a vector field can be derived in a manner very similar to the case of a scalar field, but this time with the inclusion of a dot product. Again using the above definitions of F, C and its parametrization r(t), we construct the integral from a Riemann sum.**Line Integrals of Vector Fields Oregon State University**

Line integrals of vector fields extend to three dimensions. If F =

, then In the figure above it is shown that C is traversed in the counter clockwise direction.**Line integrals and vector fields (video) | Khan Academy**

Section 5 2 : Line Integrals Part I. In this section we are now going to introduce a new kind of integral. However, before we do that it is important to note that you will need to remember how to parameterize equations, or put another way, you will need to be able to write down a set of parametric equations for a given curve.
