WebNov 16, 2024 · Notice that in the case of \(L = 1\) the ratio test is pretty much worthless and we would need to resort to a different test to determine the convergence of the series. Also, the absolute value bars in the definition of \(L\) are absolutely required. If they are not there it will be impossible for us to get the correct answer.
