## Homework Statement

Identify a

_{n}=the summation from k=1 to n of (2n)/(4k

^{2}+1) as a Riemann sum of an appropriate function on an appropriate interval and find the limit as n approaches infinity of a

_{n}.

## Homework Equations

There is no interval givien so I assume its from 0 to 1.

## The Attempt at a Solution

I only got up to 2n/(4(k/n)^2+1) and I'm not sure what to do from there.
