Asked by math!
how would I express the repeating decimal representaion of 1/9 as an infinite series using sigma notaion?
Limit of (as n-> infinity)
(Sigma) 0.1 + (0.1)^2 + (0.1)^3 +... (0.1)^n
= 0.11111.... = 1/9
I think drwis did this right, It looks like
lim n->infty Sigma i=1 to n 10<sup>-i</sup>
