Integral challenge for masters

Hi,

this integral was introduced as a problem in qualification round for regional olympiad. It took me an hour to solve. Can you solve it too?

I'm looking for your suggestions,
Izmael

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Can't find any benefit on your answer. I know, there exist many same solutions on the internet for this problem. It should be a challenge. So you can bring new inovative approach to solve this.

Your third link is not correct. There's a function sin(ln(x)), which is a bit different.

My approach was about using the exponential

Then you already knew all those ways? As you know my German is not good. But I thought they were Wunderbar!
