# Integration by parts – Why this method?

The simple answer to this question is “we have no choice”.  Sometimes it is not possible to use other integration techniques such as U substitution.  Integration by parts is one of the longer techniques used to integrate. Therefore, if there is any other quicker method to solve a particular integral, I highly encourage you to use it.

# Integration by parts – How do I do it?

Use the formula given above if you want to integrate by parts. We are given a single function to integrate. The idea is to separate this function into a product of two functions being multiplied with each other. Don’t worry; this formula will make a lot more sense once you see it used in an example. Watch any of the tutorial videos to see this formula for yourself. Here are the integration by parts steps which are used in the video tutorials,

1. Pick f(x) and g’(x).
2. Find f’(x) and g(x).
3. Plug everything into the integration by parts formula.
4. Evaluate and simplify as much as possible.
