Webconditionally convergent. I Since the series P 1 n=1 ( 1)n n is convergent (used the alternating series test last day to show this), but the series of absolute values P 1 n=1 1 is not convergent, the series P 1 n=1 ( 1)n n is conditionally convergent. Annette Pilkington Lecture 28 :Absolute Convergence, Ratio and root test WebIf convergent, an alternating series may not be absolutely convergent. For this case one has a special test to detect convergence. ALTERNATING SERIES TEST (Leibniz).
