The forum discussion focuses on determining the positive values of b for which the series Ʃ bln(n) converges, with bounds from n=1 to infinity. The primary tools discussed for this analysis are the Direct Comparison Test and the Limit Comparison Test. Participants emphasize transforming the series into a more recognizable form, suggesting the manipulation of b into the form b=e^ln(b) to facilitate comparison. The conclusion drawn is that understanding these tests is crucial for establishing convergence criteria for the series.
PREREQUISITESStudents and educators in calculus, particularly those focusing on series convergence, as well as mathematicians interested in advanced series analysis techniques.

Find all positive values of b for which the series Ʃ bln(n) converges. Bounds are from n=1 to infinity.
Homework Equations
The assignment is for Direct Comparison Test and Limit Comparison Test.
The Attempt at a Solution
I don't know where to begin. Using a comparison test would only indicate convergence or divergence. It seems like it might be a geometric series, but I'm not sure.
