Hello, Paul Stansell paulstans...@gmail.com writes: I may be under a misapprehension, but I expected the pdf output (created by C-c C-e l p) from the attached org file to show similar results for both lines. Instead, however, the simple x^2 outside of the verbatim environment puts the caret above the 2 even though I have set #+OPTIONS: ^:nil This seems to be because org-mode exports x^2 as x\^2 in the tex file. I think exporting it as x\^{}2 would give a better result. This should be now fixed. Thank you for reporting this. Regards, -- Nicolas Goaziou

### Re: [O] unexpected appearance of x^2 in pdf file

Hi Nicolas, Thanks for fixing that last problem, that's great! I've also come across a couple of other unexpected results exporting other latex equations to pdf. Examples are given in the attached org file. Both are quite trivial with easy work-arounds. In both cases, because the embedded png equations (displayed by C-c C-x C-l) are formatted correctly, the problem in the exported pdf file might go unnoticed.

In the second case, the second line defines a list item, which has precedence over any LaTeX snippet. \[ x = \begin{array}{cc} y u \\ z v \end{array} \] \[ x = \begin{array}{cc} y u \\ z v \end{array} \] I think this is because of a limitation on the number of lines a LaTeX snippet can span across (IIRC, 3 is the maximum). In both cases, I suggest to use LaTeX environments instead: \begin{equation*} x = y + 1 \end{equation*} and \begin{equation*} x = \begin{array}{cc} y u \\ z v \end{array} \end{equation*} Regards, -- Nicolas Goaziou

### Re: [O] unexpected appearance of x^2 in pdf file

Nicolas, \[ x = y +1 \] \[ x = y + 1 \] This is to be expected. In the second case, the second line defines a list item, which has precedence over any LaTeX snippet. Okay, I realised it was switching to the itemise environment, but I didn't know it took precedence over the latex environment. \[ x = \begin{array}{cc} y u \\ z v \end{array} \] \[ x = \begin{array}{cc} y u \\ z v \end{array} \] I think this is because of a limitation on the number of lines a LaTeX snippet can span across (IIRC, 3 is the maximum). Maybe, but I see the same problem with the following two line example \[ x = \begin{array}{cc} z v \end{array} \] In both cases, I suggest to use LaTeX environments instead: \begin{equation*} x = y + 1 \end{equation*} Yes, I tried that, but as I understand it I need to \usepackage{amsmath} to access the latex equation* environment. But then I get an error about Command \iint already defined. I tried the solution described at http://www.tex.ac.uk/cgi-bin/texfaq2html?label=alreadydef, but it didn't work for me. Anyway, never mind, these are all quite trivial points. Thanks very much for your help, Paul

Okay, I realised it was switching to the itemise environment, but I didn't know it took precedence over the latex environment. Technically, this is a latex fragment, not a latex environment (which is what I suggested to use). The difference is that the former is inline (i.e. it is contained in a paragraph) whereas the latter isn't. Non-inline elements always have precedence over inline ones. \[ x = \begin{array}{cc} y u \\ z v \end{array} \] \[ x = \begin{array}{cc} y u \\ z v \end{array} \] I think this is because of a limitation on the number of lines a LaTeX snippet can span across (IIRC, 3 is the maximum). Maybe, but I see the same problem with the following two line example \[ x = \begin{array}{cc} z v \end{array} \] I see. This should be fixed. Thanks for insisting.

A package is conflicting with amsmath, probably wasysym. Try to add nointegrals option to wasysym in `org-latex-default-packages-alist'. Regards, -- Nicolas Goaziou

### [O] unexpected appearance of x^2 in pdf file

Dear list, I may be under a misapprehension, but I expected the pdf output (created by C-c C-e l p) from the attached org file to show similar results for both lines. Instead, however, the simple x^2 outside of the verbatim environment puts the caret above the 2 even though I have set #+OPTIONS: ^:nil This seems to be because org-mode exports x^2 as x\^2 in the tex file. I think exporting it as x\^{}2 would give a better result. Is there another way to get the appearance I'm looking for without using the verbatim environment? Thanks for your advice, Paul PS.
