With Line Integrals we will be integrating functions of two or more variables where the independent variables now are defined by curves rather than regions as with double and triple integrals. We will also investigate conservative vector fields and discuss Green’s Theorem in this chapter.
With line integrals we will start with integrating the function \(f\left( {x,y} \right)\), a function of two variables, and the values of \(x\) and \(y\) that we’re going to use will be the points, \(\left( {x,y} \right)\), that lie on a curve \(C\).
The line integral of \(f\) with respect to \(y\) is, \[\int\limits_{C}{{f\left( {x,y} \right)\,dy}} = \int_{{\,a}}^{{\,b}}{{f\left( {x\left( t \right),y\left( t \right)} \right)y'\left( t \right)\,dt}}\]
Line Integrals Vector Fields – In this section we introduce the concept of a vector field. Line Integrals – Part I – Here we will start looking at line integrals. In particular we will look at line integrals with respect to arc length.

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.

Notes on Line Integrals. Suppose ~F = hF1; F2; F3i is a vector eld and C is an oriented curve given by a position vector ~r. We can think of the vector eld as \pushing" something along the curve.
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.
