How to look up a symbol?
Why can I only use some capital greek letters inside my equations?
I want to use the big rho (\Rho
) in my document but can not find a package which provides that char. It is not in the default math package.
Is there a package with extended greek letters? Like here: http://en.wikibooks.org/wiki/LaTeX/Mathematics#List_of_Mathematical_Symbols

As @Seamus correctly points out, capital Rho has the same glyph as capital P. You can put
\newcommand{\Rho}{\mathrm{P}}
into your preamble to make the macro\Rho
avialable. The usage of\mathrm
is necessary if you use default math alphabets, because all greek capitals are typeset in up-right font.List of those Greek letters whose capital variants coincide with latin capitals:
Plus remember that lowercase omicron looks exactly like
o
(and should be typeset by normal math font, i.e., without\mathrm
).
