sum (summation)

  • General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

  • In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
  • Syntax for summation symbol:

$$\bigsum_{i=k}^{n}$$   gives  

\bigsum_{i=k}^{n}

and

$$\sum_{i=k}^{n}$$   gives 

\sum_{i=k}^{n}

  • Use font size commands for a nicer picture:

$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$   gives  

\LARGE\bigsum_{\small{i=1}}^{\small{n}}

and

$$\large\sum_{\small{i=1}}^{\small{n}}$$   gives 

\large\sum_{\small{i=1}}^{\small{n}}

tau (lower case greek letter)

$$\tau$$ gives \tau

theta (lower case greek letter)

$$\theta$$ gives \theta

Theta (upper case greek letter)

$$\Theta$$ gives \Theta

times

$$a\times~b$$ gives a\times~b
