I have to perform integration of very large equation in Loop

I am trying to perform integration of very large function in loop

where x& y are zero , i have to perform intgration in loop with respect to z.

I have tried with Ai & Bi writting seprtaely and substituitng in eqution on top but not able to perfom integrtation , but able to perform by writting A & B in equaiton 1 but that make the equation very long

Should every possible expression you write down, long, or short, have an analytical integral? int seems to be unable to do so. Of course, that does not mean something does not exist, only that int was unable to compute the result you want. But not all questions have a solution.

Ifr you substitute numerical values, then you can comute a NUMERICAL integral, of course. That will be entirely possible to do.
