In this tutorial we shall another important integration that is integral of over plus squared; this integral is also using as an important formula.
The integral of is of the form
To prove this formula, consider
Using the derivative formula , we have
Integrating both sides of equation (i) with respect to , we have
As we know that by definition integration is the inverse process of derivative, so we have
As we know that derivative of
This formula can also be written as
