can you solve this integral :

You're welcome.

O.K. give me a bit of time to write it out in full - it's pretty long. Back to you soon.

wolframe can solve it too but what i am searching is the method and not the result ;)

I finally tried x = sqrt(2)tan(t). It was a computational headache, but here it is in all of it's glory.
