Decompose into partial fractions and look here:
Convergence of the series 1 / n(n+2)
Given U_{r} = 3/ (r^{2}+3r)
I have simplified ^{n}∑_{r=1} U_{r} in terms of n by expressing in partial fraction.
Determine the value of ^{∞}∑_{r=1} U_{r} , deduce the value of ^{∞}∑_{r=2 }U_{r+1}
I just don’t know how to deduce . Can anyone explain to me ?
