Hello all who read,(adsbygoogle = window.adsbygoogle || []).push({});

I was reading along in the book Advanced Calculus by Frederick S. Woods today and came upon this technique. I played with it a little on some sample problems, but I still cannot figure out what it has any relation to.

My questions I guess are that,

(1) what does this method help to accomplish

(2) Do I have to differentiate the final result to have a "real" answer

(3) Why is the end result seem only related to the beginning by an integration operation

I may just be completely lost, and all these things be trivial. but any help would be great, thanks!

Here is a link to an example http://mathworld.wolfram.com/IntegrationUndertheIntegralSign.html" [Broken]
