How the fuck do you even do this?
I tried to do it the way you normally do the '2ab' becomes - 1/2 so it can turn the 1 into 1/2 but I got stuck regardless.

Wolframalpha got to the same integral. Maybe I'm on the right way.

Nice to see you here, Cleo.
I'm counting on you.

substitute z = 2a sinh x
You get
Integral 1/sqrt(1+z^2)*1/sqrt(4a^2 + z^2) dz
