Homework Equations
The Attempt at a Solution
I'm not sure how it wants us to do it; do we use sigma notation or the general right/left-hand sums?
Using sigma notation, delta T = 10-5/n
T0= 5/n (?)
T1= 10/n
Ti = 5i/n
5/n[tex]\sum6(5i/n)^3 -2[/tex]
750/n^4 -2 (Sigma) i^3
I'm not sure if I can bring the 2 out like that, and I'm also not sure what i^3 equals (is it (n(n+1)/2)^3?)
