Where does it come from?

I don't know to evaluate the sum by hand.

After going through techniques to sum the series I saw that few sums were easy to solve as integrals and vice versa!

Hi;

I did not think about doing that.

Okay, it works like a charm sometimes!

I wonder where they got that integral from in the first place.

Maybe some randomly thought out integral.

I have got a few when trying differentiation under the integral sign.

I agree, it is hard to imagine that is connected to a real problem.

It is mentioned in a couple of places that talk about experimental math but I can not think of them offhand.

Thanks for coming in.

I am sorry but I am unable to find any of the links of the original paper.
