Take a look at the change of variables formula for integration in R n (the Jacobian formula) and you will see it behaves the way differential forms do. The impression one gets is that differential forms were created to simplify integration.

Integration of differential forms is well-defined only on oriented manifolds. An example of a 1-dimensional manifold is an interval [a, b], and intervals can be given an orientation: they are positively oriented if a < b, and negatively oriented otherwise.

There are several equivalent ways to formally define the integral of a differential form, all of which depend on reducing to the case of Euclidean space. Let U be an open subset of Rn. Give Rn its standard orientation and U the restriction of that orientation.

Integration of a function that is done within a defined and finite set of limits, then it is called definite integration. The basic formula for the differentiation and integration of a function f (x) at a point x = a is given by, Further, in the next section, we will explore the commonly used differentiation and integration formulas.
