Small challenge for you:
$$\int_0^\infty\frac{\arcsin(\sin^2 x)}{x^2}\mathrm{d}x=2\ln(1+\sqrt2)$$

I've decided to reduce all my interactions with this site down to just reading and voting. It's not like I've stopped my contribution, I have 3 reasons to do this:

1. Most new questions are so boring.
2. I have a lot to study on my own.
3. I don't think I have enough quality to write a good question or answer.

I've got 100+ actions so far, but most of them are just me yapping around, thinking that I could edge like a pro mathematician, no cap. Pls don't think of me as a sussy baka, I've been around for 6-7 years, I know how to rizz.
