Well, so I really want to integrate what's shown in the title:(adsbygoogle = window.adsbygoogle || []).push({});

i.e.

[tex]\int \frac{dx}{(x^2+y^2)^\frac{3}{2}}[/tex]

Now, I know there are quite a few straightforward answers to this. But what I really want is how people who do math got this formula in the first place. I don't just want a formula that seems to have come from a serendipitous accident or something. Please tell me how toderivethe answer.

(You might have guessed this has something to do with electric fields)

Thank you for helping.
