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.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

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!
