While preparing a task for my students I noticed Alpha gives "Sum does not converge" for an alternating series which obviously converge conditionally by Leibnitz theorem. Here's what Alpha wrote:
sum_(n=1)^infinity ((-1)^n log(n))/n (sum does not converge)
Am I doing something wrong?
Alpha does interpret correctly my input, but gives the wrong answer.
I would appreciate yr help before sending my students to use Alpha for this task. Tnks. Dvora
