This command generates the summation operator,
. The difference between this and \Sigma
, which generates the capital letter
, is that \sum
appears larger, and that it supports the limits to be displayed below and above the symbol.
The following example illustrates the difference between \sum
and \Sigma
.
This examples are written as:
\sum_{n=1}^\infty
\qquad
\Sigma_{n=1}^\infty\frac{1}{2^n}=1
