MathJax

MathJax is software for typing formulas . 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\[\int_a^b f(x)\mathrm d x\]

In TORI, the use of dollar caused confusion at the automatic treatment of text by robots. For this reason, here, the beginning of the math mode is marked as

\(

and the end of the math (and return to the normal text formatting) is denoted with

\)

In such a way, the math mode can be switched on and switched out with standard wikimedia notations

\( ... \)

nomathjax

In Wo, MathJax is supported by default. It can be desactivated with command nomathjax, just type \)<\! \rm nomathjax \!>\(. After such a command, the dollars loss their usual value '"`UNIQ--ref-00000006-QINU`"' and are interpreted as ordinary characters; they can be typed in any amount without any special effect. In such a way, you may print so many dollars as you need. Then the MathJax can be activated again with command \)<\! \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 . 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.

Numbering of formulas, again

Sorry, there is some problem with it

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 . Similar examples are shown below.

Here is a labeled equation\[f_1(x)=\frac{x+1}{\sqrt{1-x^2}}\label{eq:ref1} \]

or

\[ f_1(x)=\frac{x+1}{\sqrt{1-x^2}}\label{eq:ref2} \]

or

\( f_1(x)=\frac{x+1}{\sqrt{1-x^2}}\label{eq:ref3} \)

or

$$ f_1(x)=\frac{x+1}{\sqrt{1-x^2}}\label{eq:ref5} $$

it is labeled as "ref1", and here is reference to ref1: \eqref{eq:ref1}.

\refeq{eq:ref1}.

In the similar way, one may label another equation, \(f_2(x)={x+2\over\sqrt{1-x^2}}\label{eq:ref4}\) it is labeled as "ref2", and here is reference to ref2: \eqref{eq:ref4}. 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.
