How do you do the limit comparison test for this problem #sqrt ( (n+1)/ (n^2+2))# as n goes to infinity? May 2, 2021 · In Stewart's calculus, there is a proof for the direct comparison test and I was wondering why the contrapositive wasn't used. Although I think I get the proof, I don't know why it's necessary. Below is my reasoning: From part (i), if ∑an ∑ a n is convergent then ∑bn ∑ b n is convergent. So, by contrapositive, if ∑bn ∑ b n is not ... The limit comparison test is another test that can be used to determine series convergence and works in many of the same situations that the direct comparison test is used.
