Transcribed Image Text:Strategy D5 Null/non-null sequence
.To show that the sequence (an) is null,
rearrange the inequality |an| < ɛ to find an
integer N (generally depending on ɛ) such
that an <ɛ, for all n > N.
To show that the sequence (an) is not null,
find one value of e > 0 for which there is no
integer N such that an < e for all n > N.
