4.1 Line Integrals
In this section we will define and learn how to evaluate the line integrals of the form
Before discussing the line integrals, however, let’s review the concept of indefinite and definite integrals.
4.1.1 Indefinite and Definite Integrals
We will first introduce the indefinite integral and then use it to present the definite integral.
The indefinite integral can be easily defined using the concept of a derivative as follows.
Consider a function f(x). If its integral exists, denoted,
Several useful integral formulas are presented next:
If the indefinite ...
