This calculus 2 video provides a basic introduction into the absolute value theorem for sequences. If the absolute value of a sequence converges, then the sequence itself also converges.

Professor Organic Chemistry Tutor, thank you for a short and sweet video/lecture on the Absolute Value Theorem for Sequences in Calculus Two. This Theorem is built for convergence of Sequences in Calculus. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

Proof :Let's assume ε>0. Since |An| -> 0, there is n0 (natural) so that for every natural n so that n>=n0 ||An|-0|<ε <=> ||Αn||<ε <=> |Αn|<ε <=> |An-0|<ε. So for every ε>0 there is n0 so that for every natural n>=n0: |An-0| < ε. By definition, An -> 0.

At 4:40, isn't the graph of the absolute value of ((-1)^x)/x the same as the graph of 1/x?
