Now consider

Integrating both sides of equation (i) with respect to , we have

Since integration and differentiation are reverse processes to each other , so the integral sign and on the right side will cancel each other, i.e.

__Example__**:** Evaluate the integral with respect to

We have integral

Using integration of one over , we have
