If we let

**u
= f(x)** and
** v = g(x)****,**

then

**du
= f'(x) dx** and **dv
= g'(x) dx**.

Substituting these two terms in the formula for Integration by Parts, we get the following formula:

which is also called the **formula
for Integration by Parts**.

This formula is called the **formula
for Integration by Parts**.
