Homework Statement
To find convergence, why can't I divided by the largest n in the denominator in this problem: SUM n_infinity 1/(n^2 - 4n + 4) ?
its suggested to use the comparison test.
(I think SUM stands for E Reimann sum correct?)
but in this problem, I can easily find convergence by dividing by large n in the denominator: lim n->infinity 3n^2/(7n^2 + 1)
?
any explanation please. thanks.
