Homework Statement
Find the limit, as n -> infinity, of [tex]\sum_{k=1}^n[/tex]k3/n4
Homework Equations
Riemann sum: S(f, [tex]\pi[/tex], [tex]\sigma[/tex]) = [tex]\sum_{k=1}^n[/tex]f([tex]\xi[/tex])(xk - xk-1)
The Attempt at a Solution
My guess is that I should try to put this sum in terms of a Riemann sum, and then taking n -> infinity will give an integral of something. I'm just not sure what it is. Any hints? Thanks!
