We were asked to identify and rewrite the following statement. Not sure how to do a sum sign here so will just write sum for it:
sum (lower i=0)(upper 2n) (i/n)^2 (1/n) = 1/n^3[ 1^3 + 2^3 + 3^3 + ... + (2n)^2
I believe this is a Riemann Sum but not sure how to rewrite it.
The Attempt at a Solution
I have :
I'm still looking for how to rewrite.
