I've got a function [tex] \int e^{-x}sinx dx [/tex]
From what I know, only functions which has one or more products with a finite number of successive differentials can be evaluated using integration by parts. Because for [tex]\int v du [/tex]in our choice of du, we want to cut down on the number of times we have to evaluate it using integration by parts again.
Since both [tex]e^{-x}[/tex] and [tex]sinx[/tex] have infinite nos. of successive differentials, how do i evaluate that?
