I know in general how to prove if sequence is null or not . But here is my confusion
- method in the textbook I am reading - asks that to prove that any sequence is null we must show that for each ε>0, there is an integer N such that modulus of the given sequence is < ε, for all n>N
now I also understand this but my dilema is
taking modulu say for example given sequence is
{(1+(-1)^n)/(n+(-1)^n )}
taking modulus gives:
|(1+(-1)^n)/(n+(-1)^n )| is modulus 2/(n+1) ?
just not sure
