## LaTeX, MathML, PNGs [General Statistics]

Hi Shuanghe,

congratulations for mastering the nested lists in your post. I’m impressed!

» 9. It seems LaTeX expression can not be used to write math equation here.

Correct.

» Is it possible to implement it?

Theoretically yes.

BTW,

» Since there are so many members here …

Don’t overestimate that. This year so far only 122 of them were

» … and some times one has to write complicate formula it might be a good idea to be able to write equations in LaTeX.

I’m afraid users in the forum being knowledgable of

Edit: With the MathJax library (installed June 2019):

$$\left(\frac{s_{wR}/s_{wT}} {\sqrt{F_{\alpha/2},\quad{\nu_1},\quad{\nu_2}}},\frac{s_{wR}/s_{wT} }{\sqrt{F_{1-\alpha/2},\quad{\nu_1},\quad{\nu_2}}}\right)$$

$$C{V_w}=\sqrt{{e^{\sigma _w^2}}-1}$$

congratulations for mastering the nested lists in your post. I’m impressed!

- It would be possible to add GeSHi which was also used by Wikipedia. In version 2 of the forum’s scripts it turned out that the server-load can be extreme (though fine for distributed sites like WP). It lead to a workaround almost doubling the size of the MySQL-database (one table containing original posts and another one linking to rendered PNGs; example-post). I didn’t like that and decided to stay with the v1.x-branch.

- Another –
*desirable*– option would allow to embed MathML in (X)HTML. Currently the support by browsers is limited (see here; unfortunately 11.1% of users of the forum still on IE).

- Client-side solutions (KaTeX, MathQuill, MathJax, SHJS, …) are a not so nice because some companies’ IT-folk restrict JavaScript on user’s machines.

_{}⇒ DVI ⇒ Ghostscript ⇒ grayscale (4 or 8 bit) PNG with alpha-transparency enabled and upload/link the file here. Example:Drawbacks: If images are disabled in the browser only the image’s attribute`alt="[image]"`

is displayed. GeSHi would come up with `alt="\left ( \frac{s_{wR} / s_{wT} } {\sqrt{F_{\alpha/2}, \quad {\nu_1}, \quad {\nu_2}}}, \frac{s_{wR} / s_{wT} } {\sqrt{F_{1-\alpha/2}, \quad {\nu_1}, \quad {\nu_2}}} \right )"`

. The former is non-informative and the latter confusing to anybody not familiar with the syntax of *A*–_{M}S_{}.BTW,

*simple*formulas in the forum can be constructed by means of UTF-8 characters and BB-Codes,*e.g.*,*CV _{w}* = √ℯ

^{σ²w}− 1

*active*(at least one post). The forum is a rather exclusive club; ten nerds (0.1%) are guilty for 55% of all posts.» … and some times one has to write complicate formula it might be a good idea to be able to write equations in LaTeX.

_{}are in the minority… BTW, I once wrote a manuscript in MiKT_{E}X according to the publisher’s templates only to learn that they required bloody M$-Word in the meantime. Although I used MathType don’t ask me how the paper looked at the end.Edit: With the MathJax library (installed June 2019):

$$\left(\frac{s_{wR}/s_{wT}} {\sqrt{F_{\alpha/2},\quad{\nu_1},\quad{\nu_2}}},\frac{s_{wR}/s_{wT} }{\sqrt{F_{1-\alpha/2},\quad{\nu_1},\quad{\nu_2}}}\right)$$

$$C{V_w}=\sqrt{{e^{\sigma _w^2}}-1}$$
