Popis: | Throughout this note we deal with a series Σan of positive terms. The following tests for the convergence of this series are well-known.Test 1. (Ratio test). LetThen, if K < 1, Σanconverges, while if K > 1, Σandiverges.Test 2. (Root test). LetThen, if K < 1, Σanconverges, while if K > 1, Σandiverges. |
