## What is the line integral of a vector field?

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. One can also integrate a certain type of vector-valued functions along a curve.

## What are line and surface integrals explain them with examples?

A line integral is an integral where the function to be integrated is evaluated along a curve and a surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral.

Which of the following is an example of vector field?

A gravitational field generated by any massive object is also a vector field. For example, the gravitational field vectors for a spherically symmetric body would all point towards the sphere’s center with the magnitude of the vectors reducing as radial distance from the body increases.

How do you do line integrals?

This is red curve is the curve in which the line integral is performed….Definition of a Line Integral.

requirement simple integrals For line integrals
2 the equation of the path in parametric form (x(t),y(t))
3 bounds in terms of x=a and x=b the bounds in terms of t=a and t=b

### What do line integrals represent?

A line integral allows for the calculation of the area of a surface in three dimensions. Line integrals have a variety of applications. For example, in electromagnetics, they can be used to calculate the work done on a charged particle traveling along some curve in a force field represented by a vector field.

### What is the difference between line integral and double integral?

Our main objects of study will be two types of integrals: Double integrals, which are integrals over planar regions. Line or path integrals, which are integrals over curves.

What is the difference between definite and line integral?

Line integrals has a continuously varying value along that line. Definite integrals express as the difference between the value of the integral at specified appear and lower limit of the independent variable.
