Synopsis
Help:WikiPlugin to display mathematical formulae in a Wiki page.
Usage
<?plugin TeX2png text="$$(a+b)^n=\sum_{k=0}^n{n\choose k}a^k b^{n-k}$$" ?>
gives
Cannot run TeX2png plugin, “/usr/bin/latex” does not existArguments
There is only one argument which is the text of the mathematical expression. This text must be enclosed by a dollar $ within a paragraph or two dollars $$ on a separate line. In the last case, all is centered.
To write mathematical formulae, the syntax is the one
of 
LaTeX.
Caveats
This plugin is only to produce readable mathematical formulae. Any other text is not allowed : so if an expression is not enclosed by dollars then it will be displayed by a red text. It is all the same possible to display raw text as Cannot run TeX2png plugin, “/usr/bin/latex” does not exist by using :
<?plugin TeX2png text="$\textrm{\LaTeX}$" ?>
This plugin is not able to produce sophisticated mathematicals texts with links, cross references... For that, you can use for example LaTeX2html.
Examples
Some Greeks letters : Cannot run TeX2png plugin, “/usr/bin/latex” does not exist, Cannot run TeX2png plugin, “/usr/bin/latex” does not exist, ... and a formula Cannot run TeX2png plugin, “/usr/bin/latex” does not exist to test display in a paragraph.
Exercise 1 Consider the function Cannot run TeX2png plugin, “/usr/bin/latex” does not exist
- Give the largest real domain for which f(x) is well defined.
- Give a domain on which the function is one-to-one. Using this domain derive a formula for the inverse function Cannot run TeX2png plugin, “/usr/bin/latex” does not exist.
- Calculate the derivative f'(x).
Exercise 2 Consider the function :
Cannot run TeX2png plugin, “/usr/bin/latex” does not exist- Show that for all r > 0 :Cannot run TeX2png plugin, “/usr/bin/latex” does not exist Help : you can use polar coordinates.
- Hence find the limit of Cannot run TeX2png plugin, “/usr/bin/latex” does not exist as x tends Cannot run TeX2png plugin, “/usr/bin/latex” does not exist.
