In general is... (1)
... so that is... (2)
Using (2) we obtain... (3)

Guys, you're not proving at all that it converges
I don't undestand what needs further demostration...
... may be this step?... (1)
... or may be this?... (2)

chisigma : you're not proving that it converges, you're supposing it does and calculates it as if it was the case.
the first integral converges by limit comparison test with now put in this integral to get which exists since the integrand has limit as (1)
for we have and (2)
in your integral put and get then by (1) and (2) the conclusion follows.
