comment simplifying the range of two definite integrals
right of course, caught me commenting before my second cup of coffee. I'll point out you can show this more simply as Integrate[ f[x] , {x, 0, 1} ] + Integrate[ f[x] , {x, 1, t } ] does not simplify under any assumptions I can think of.

comment simplifying the range of two definite integrals
mathematically you need 0<=t<=1 to consolidate that to a single integral (from 0 to t). (I don't know if mathematica will do the simplify even under that assumption though)

comment simplifying the range of two definite integrals
to further simplify you need to know something about the range of t. try specifying assumptions.

comment Find all roots in range
just looking at the comments @matin maybe should clarify the question as he seems to be aware of ZetaZero and looking for an alternative for some reason.

comment Find all roots in range
Solve gives the result that the roots are +/-Im[ZetaZero[i] - 1/2] for any i>0 (plus the trivial roots) .. at least as I read the question/comments he wants to find the roots without using ZetaZero

comment Find all roots in range
Note this just returns a result in terms of ZetaZero..

i'm going to guess you have a Print[] in the do?
