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: $\int_{-\infty }^{\infty }e^{-x^{2}}\;dx=\sqrt{\pi }$ And the HTML code to put in your post for that example is:
<img src="http://www.forkosh.dreamhost.com/mimetex.cgi?\int_{-\infty }^{\infty }e^{-x^{2}}\;dx=\sqrt{\pi }"/>


(Personally I find the image generated by the service mentioned in the other thread to be a bit prettier.]

Thanks go to Kambiz and Sneftel, who originated this information for me/us!

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}}$$Which is plain html (no img). #### Share this post ##### Link to post ##### Share on other sites So Mathjax seems good, since it doesn't require relying on any no-very-permanent external web sites (I just see broken image links above). But I want to write inline maths, rather than having it split into a new paragraph. Mathjax docs say I should use single  to wrap it, but that doesn't see to work here. I want to define f(x) = x mid-sentence.  I want to define f(x) = x mid-sentence. Defining$$f(x) = x$$this way take too much space when you do it loads.  Defining$$f(x) = x this way take too much space when you do it loads.

Is there some config someone can change to make it work?
