P

parentheses

  • Syntax: \left(...\right) or ...
  • Ex.: $$2a\left(b+c\right)$$ gives

2a\left(b+c\right)

phi (lower case greek letter)

$$\phi$$ gives \phi

Phi (upper case greek letter)

$$\Phi$$ gives \Phi

pi

$$x=\pi r^2$$ is x=\pi r^2

pi (lower case greek letter)

$$\pi$$ gives \pi

Pi (upper case greek letter)

$$\Pi$$ gives \Pi

plus

$$+$$ is +

plus minus

$$a\pm~b$$ gives a\pm~b

product

  • 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 product symbol:

$$\bigprod_{i=k}^{n}$$   gives  

\bigprod_{i=k}^{n}

and

$$\prod_{i=k}^{n}$$   gives 

\prod_{i=k}^{n}

  • Use font size commands for a nicer picture:

$$\LARGE\bigprod_{\tiny{i=k}}^{\tiny{n}}$$   gives  

\LARGE\bigprod_{\tiny{i=k}}^{\tiny{n}} 

and

$$\large\prod_{\small{i=k}}^{\small{n}}$$   gives 

\large\prod_{\small{i=k}}^{\small{n}}

psi (lower case greek letter)

$$\psi$$ gives \psi
