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\[\int_a^b f(x)\mathrm d x\]
In TORI, the use of dollar caused confusions at the automatic treatment of texts 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 TORI, MathJax is supported by default. It can be desactivated with command nomathjax, just type
<nomathjax> ... </nomathjax>
After command "nomathjax", the
\(
is supposed to appear as it is typed.
With these commands, the line below is typed:
\( abcd^2 \)
Numbering of formulas
Sorry, after recovery in 2019-2020, this section is not yet updated.
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 [2]. 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.
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 [3]. 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.
