Question:  What is the DI method and how do you use it?
The advantage of using this method is: its easy to do integrate-by-parts mechanically. Without even needing to exert a large amount of thinking about the special circumstances of the problem.

The process is fairly quick to memorize and it is very easy to retain. After you learn it once, it will always be at your disposal as a tool for quickly and easily determining indefinite integrals that would otherwise take lot of time to find.
