LaTeX - based equations in gamedev.net forums
Folks,
There is a sticky thread in another forum that shows how you can embed fancy LaTeX-based equations in your forum posts. That functionality seems really beneficial to the math & physics forum so I'm linking to the other thread here. Here is a link to that thread:
LaTeX - math equations support?
There is another service available that can also do this. Here is an example using the other service:
And the HTML code to put in your post for that example is:
(Personally I find the image generated by the service mentioned in the other thread to be a bit prettier.]
You may use the eqn tag and wrap it around single or multi-line LaTeX formulas now:
[eqn]\left| \begin{array}{cc} x_{11} & x_{12} \\ x_{21} & x_{22} \end{array} \right|[/eqn]
[eqn]
\begin{bmatrix} xz & xw \\ yz & yw \end{bmatrix} = \left
[ \begin{array}{c} x \\ y \end{array} \right] \times \left
[ \begin{array}{cc} z & w \end{array} \right]
[/eqn]
Lucky, since the new forum breaks support for non-standard image file names, which means that we can't use *any* 3rd-party embedding service (including all the old latex posts).
I came here looking for a way for embedding formulas in the posts. Gamedev now supports Mathjax, so Latex formulas can be easily embedded by enclosing them in double dollar signs ($$).
So writing this in the post:
$$\sqrt{(F{_{x}})^{2}+(F{_{y}})^{2}}$$ Results in this:
$$\sqrt{(F{_{x}})^{2}+(F{_{y}})^{2}}$$
Which is plain html (no img).
So Mathjax seems good, since it doesn't require relying on any no-very-permanent external web sites (I just see broken image links above).
But I want to write inline maths, rather than having it split into a new paragraph. Mathjax docs say I should use single $ to wrap it, but that doesn't see to work here.
Is there some config someone can change to make it work?

I want to define $f(x) = x$ mid-sentence.
Defining $$f(x) = x$$ this way take too much space when you do it loads.

I figured it out. Mathjax default config is not to recognise single $ because people use it too often for currency. Go figure.
Anyway, here's how to do it:

Defining \(f(x) = x\) mid-sentence.
You can also use the similar \[f(x) = x\] to split into a new paragraph.
I found this guide to the Mathjax Tex syntax very helpful - I thought I'd put it here, as other people might find it useful too.
