Find $limlimits_nrightarrowinftysumlimits_k=1^nfrac1n+sqrt(k^2-k+1)$.




I observed it is a Riemann integral and can be written as $frac1nsumlimits_k=1^nfrac11+sqrtleft(left(fracknright)^2-frackn^2+frac1n^2right)$, and for $x_i=frackn$ this is a Riemann sum. I have problems with passing to the limit as I obtain $int_0^1frac11+sqrtx^2-fracxn+frac1n^2dx$. can I apply this limit for the integral as to reduce the $frac1n$ as n converges to $infty$?

If you evaluate a limit as $n$ goes to infinity, then the result should not depend on $n$.



Instead, note that
$$frac1nsum_k=1^nfrac11+fracknleq frac1nsum_k=1^nfrac11+sqrtfrack^2n^2-frack-1n^2leq frac1nsum_k=1^nfrac11+sqrtfrac(k-1)^2n^2=frac1nsum_k=0^n-1frac11+frackn.$$
Now use the Riemann sum approach for the left-side and the right-side.



Can you take it from here?
