Hello,

 or + is a workaround.

Actually, it's not erroneous. Plain lists in Org mode have precedence
over paragraphs. It may be surprising sometimes but it would be the same
if you had:

\[
some equation
* This would be an headline
some other equation
\]

Re: [O] Inline LaTeX fragments in emacs buffer

[Dov Grobgeld]

Thanks for the help. It makes my coursera ml-class notes easier to read.

One issue I had when I tried exporting to HTML with the dvnpng option the
following equation:

\[
J(\theta) = - \frac{1}{m} \left[\sum_{i=1} ^m y^{(i)} \log
h_\theta(x^{(i)})+(1-y^{(i)})\log(1-h_\theta(x^{(i)}))\right]
  + \frac{\lambda}{2m}\sum_{j=1} ^n \theta_j ^2
\]

in the png output I got the following trailing text:ORG-LIST-END-MARKER .
Is this a known bug?

Regards,
Dov

 I set C-c P as a global key-binding for org-preview-latex-fragment and
 C-c p to org-ctrl-c-ctrl-c. Then I can preview equations all equations in
 ANY buffer with C-u C-u C-c P. It's great to write equations in comments
 of some programming buffer (no matter which programming language) and being
 able to render the equations right there.

  Yes, you can produce a preview image with C-c C-x C-l.

I don't think breaking the equation into multiple lines is supported by
org. It may work but it is not guaranteed. I write the whole equation as a
single line and I don't have any problems, besides the equation being
harder to read and modify later.

Ps: I have the same use case scenario: writing notes with equations when I
watch the classes of the coursera courses. I also write the relevant
equation in a comment in the MATLAB/Octave when implementing the
programming exercises.

[O] Inline LaTeX fragments in emacs buffer

[Dov Grobgeld]

Is there any way of getting org-mode to display inline LaTeX fragments in
the emacs buffer? E.g. I would like to be able to type:

The size of the hypotenuse is $\sqrt{a^2+b^2}$

and then the buffer immediately shows:

The size of the hypotenuse is √a²+b²

where √a²+b² is a png image rendered via dvipng.

I assume a toggle would switch between either seeing the formula or seeing
the source of the formula, just like for the display of inline images.
Also, pressing a backspace when the cursor is at the end of the formula
should erase the trailing $ sign, and turn off image display of the
formula, just like for [[links][name]].

Has anything like this been implemented?
