    How have you come across this? Are you aware of the Laurent expansion of the zeta function centred at 1?

    I tried to used substitution but it does not work out

    If it makes sense, then you mind find equation (1) from

    Actually thinking further, that link is likely overkill as the answer is Euler's constant - have you come across that?

    Yes,i use mma to get the answer. It is Eular constant.But i still believed it could be solved by zeta function.

    Well that limit is the constant coefficient in the Laurent expansion of the zeta function centred at 1. Does that help?

    It's very hard to help, when you've not shared anything about how you met this limit or the extent of your mathematical background. I don't at the moment even know whether you know what a Laurent expansion is.

    Do you have idea using Zeta function to get the limits?
