MathJax is software for typing formulas [1]. It uses the Latex style, making the source of the web-article compatible with style of a scientific journal.
Dollar
In MathJax, as in Latex, many things are controlled by dollars.
Typing the sign of dollar, id est, \( \\) \(, switches on the mathematics mode;
then, the characters are interpreted as mathematical symbols or as the [[Latex]] commands. If the dollar appears again, it switches the control back to the normal typesetting. In such a way, to type some math and then some plain text, one needs at least two dollars. The results may look like this: \)\int_a^b f(x)\mathrm d x\(.
Typing two dollars at once, id est, \) \\( \\) \(, reserves the special line for the equation.
After to finish this equation, the double-dollar should be repeated again. The result may look as this'"`UNIQ-MathJax1-QINU`"'
=='"`UNIQ--h-1--QINU`"'nomathjax==
In [[Wo]], [[MathJax]] is supported by default.
It can be desactivated with command [[nomathjax]], just type \)<\! \rm nomathjax \!>\(.
After such a command, the dollars loss their usual value
'"`UNIQ--ref-00000002-QINU`"'
and are interpreted as ordinary characters; they can be typed in any amount without any special effect. In such a way, you may print so many dollars as you need.
Then the MathJax can be activated again with command \)<\! \rm /nomathjax \!>$.
After such a command, the dollars get back their normal meaning and ability to switch-on and switch-off the math mode.
Temporal suppressing of MathJax is essential at the including of some code in Latex and/or in PHP, where dollars are important.
Numbering of formulas
The similarity with Latex appears in the numbering of formulas. The test of equation references is suggested at http://cdn.mathjax.org/mathjax/latest/test/sample-eqrefs.html [3]. Similar examples are shown below.
Here is a labeled equation\[f_1(x)=\frac{x+1}{\sqrt{1-x^2}}\label{ref1}\\] it is labeled as "ref1", and here is reference to ref1: \ref{ref1}.
In the similar way, one may label another equation, \(f_2(x)={x+2\over\sqrt{1-x^2}}\label{ref2}\\) it is labeled as "ref2", and here is reference to ref2: \ref{ref2}. The equations should be referred one by one, for example, \ref{ref1}, \ref{ref2}. Attempts to cite them both at once is interpreted as an error \ref{ref1,ref2}, and marked with red.
