P

:
$$\Phi$$ gives \Phi
:
$$\pi$$ gives \pi
:
$$\Pi$$ gives \Pi
:
$$a\pm~b$$ gives a\pm~b
:
  • 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}}

:
$$\psi$$ gives \psi
:
$$\Psi$$ gives \Psi

R

:
$$\rho$$ gives \rho
:
  • Syntax: \left.{...\right}  (note the dot!)
  • Ex.: $$\left.{{\rm~term1\atop\rm~term2}\right}=y$$ gives

\left.{{\rm~term1\atop\rm~term2}\right}=y

(\rm~something switches to roman style)

:
  • Syntax: \sqrt[n]{arg} or simply  \sqrt{arg} for \sqrt[2]{arg}
  • Ex.: $$\sqrt[3]{8}$$ gives

\sqrt[3]{8}

  • Ex.: $$\sqrt{-1}$$ gives

\sqrt{-1}

  • Nesting of roots (and combining with fractions, ...etc.) are possible.
  • Ex.: $$\sqrt[n]{\frac{x^n-y^n}{1+u^{2n}}}$$ gives

\sqrt[n]{\frac{x^n-y^n}{1+u^{2n}}}

  • Ex.: $$\sqrt[3]{-q+\sqrt{q^2+p^3}}$$ gives

\sqrt[3]{-q+\sqrt{q^2+p^3}}
