WebIf it won't, if you converge, but it doesn't converge when you take the absolute value of the terms, then you say it converges conditionally. If it converges, and it still converges when you take the absolute value of the terms, then we say it converges absolutely. WebIn this terminology, the series (7.16) converges absolutely while the alternating harmonic series converges conditionally. Absolute convergence is a strong condition in that it implies convergence. That is, if the series ∑ ak ∑ a k converges, then the series ∑ak ∑ a k converges as well. map hays county texas https://jacobullrich.com
