A vector field attaches a vector to each point. for example, the sun has a gravitational field, which gives its gravitational attraction at each point in space. the field does work as it moves a mass along a curve. we will learn to express this work as a line integral and to compute its value. in physics, some force fields conserve energy.

Multivariable Calculus Line Integrals Over Vector Fields A Few Section 16.4 : line integrals of vector fields. in the previous two sections we looked at line integrals of functions. in this section we are going to evaluate line integrals of vector fields. we’ll start with the vector field, →f (x,y,z) =p (x,y,z)→i q(x,y,z)→j r(x,y,z)→k f → (x, y, z) = p (x, y, z) i → q (x, y, z) j → r. The line integral of the vector eld f(x;y) over the vector function r(t) is de ned: z c f dr = f(r(t)) r0(t)dt this is sometimes called a work integral. we’ll see later that line integral of a vector eld has applications beyond physics. multivariable calculus 26 130. The integrals of multivariable calculus. multivariable calculus includes six different generalizations of the familiar one variable integral of a scalar valued function over an interval. one can integrate functions over one dimensional curves, two dimensional planar regions and surfaces, as well as three dimensional volumes. 1 multivariable and vector 4.1.1 examples of vector fields. 4.4 path independent vector fields and the fundamental theorem of calculus for line integrals.

Line integrals, i the motivating problem for our development of double integrals was to nd the volume under the graph of a surface. we will now develop yet another type of integral, called a line integral. the motivating problem is as follows: suppose we have a plane parametric curve r(t) = hx(t);y(t)iand a function f (x;y). In this chapter we will introduce a new kind of integral : line integrals. 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.
