'Sigma' is to use a lot of parts. Sigma is origin mean is Greece's 18th alphabet. But, I want to introduce sigma's mean at Math.
Sigma's mean is like it "Sigma is tool about limit result about series' sum". So Example: If we think about series { an } 1/2^n so that series' infinity sum is sum_n=1^infinity 1/2^n so that limit result's sum is 1.
Sigma use three parts. First part use starting number value and Second Part use final parts number value. And final part use default number at this series.
Today, I introduce about Sigma. Please remember mean of the Sigma.
