Plugging a Sequence into a Function and Examples

in DTube6 days ago


In this video I go over Theorem 3, which states that if a sequence has a limit, then plugging it into a continuous function at that limit is the same as plugging in the limit. I will prove this Theorem in a later video. I also go over 2 examples, one on applying Theorem 3, and another on using the Squeeze Theorem to find the limit of a sequence.
