Let us learn about integration by part

If

1 of very common mistake students usually do is

Take

A technique applied to find the integral of the product of 2 functions by means of an identity involving another simpler integral; for functions of 1 variable the identity

**Integration by parts**is referred as a rule that transforms the integral of products of functions into other ideally simpler integrals. The rule begins from the product rule of differentiation.If

*u*=*f*(*x*),*v*=*g*(x) and the differentials*du*=*f*'(*x*)*dx*and*dv*=*g*'(*x*)*dx*, then the product rule in its easiest form is:*g*(*x*) =1 &*f*(*x*) =*x*. Therefore, 1 may wonder what to do in this case. A partial solution is given by what is called**Integration by Parts**. In order to understand this technique, recall the formulaA technique applied to find the integral of the product of 2 functions by means of an identity involving another simpler integral; for functions of 1 variable the identity

is for functions of several variables the technique is tantamount to using Stokes' theorem or the divergence theorem.

*Integration by parts*is an integration technique which is depends on the Product Rule for derivatives.
