The integration of is another important formula of integral calculus. This integral belongs to the exponential formulae and is one of the simplest formula of integration.
The integration of e power x is of the form
Using the derivative formula , we have
Integrating both sides of equation (i) with respect to , we have
Since integration and differentiation are reverse processes to each other, the integral sign and on the right side will cancel each other out, i.e.
Example: Evaluate the integral with respect to
We have integral
Using integration of e power x, we have
