# How to show the symbol of pi

#### Chikis

How do I show the left and right bracket using latex, and also the pi symbol?

Left and right [ ], sized to whatever is in them is done by \left[ and \right]. Similarly, for ( ) and { }, use \left(, \right), \left{, and \right}. And, as V8Archie said, \pi for pi:

$$\displaystyle \left{ \pi \right}$$ gives $$\displaystyle \left{ \pi \right}$$

That would be \left \{
\left \{ \pi \right \} gives $$\displaystyle \left \{ \pi \right \}$$

This only has to be done for the curly brackets.

I think you still have to re-edit or repost since what you posted is not displaying correctly.

Code:
$\left[ \pi \right]$
gives $$\displaystyle \left[ \pi \right]$$

Some implementations of LaTeX, including mimeTeX, which is currently used by this website if you use latex tags rather than math tags, allow the use of \left{ and \right}.

For coding implemented by MathJax, such as anything enclosed in math tags, the rules are stricter and it's necessary to use \left\{ and \right\} (or just \{ and \} if the displayed symbols are not required to be automatically resized). MathJax requires the extra "\" symbols only in conjunction with curly brackets (sometimes called braces) that are to be displayed, and doesn't accept them in conjunction with square brackets or parentheses.
