Chapter 9, Problem 108(choose chapter or problem)
Using a Series Show that if
\(\sum_{n=1}^{\infty} a_{n}\)
is absolutely convergent, then
\(\left|\sum_{n=1}^{\infty} a_{n}\right| \leq \sum_{n=1}^{\infty}\left|a_{n}\right|\).
Text Transcription:
Sum_n=1^infinity a_n
|Sum_n=1^infinity a_n| leq Sum_n=1^infinity |a_n|
