My question is similar to this question, but I don't know how to apply the solution to a Jupyter Notebook. When I use the \square or \Box symbol in a Markdown cell, it comes out in italics:
How can I correct this in a consistent manner? It would be great if I could do it in a global manner rather than opting for a per-notebook fix.

Apologies in advance because I do not know how to communicate this question via code.
I have an R Notebook document with some latex (maybe not formally latex, but it's mathematical notation). Previously, when the document was in visual mode, I could see my notation inside the notebook. Now, when I compile the document to a pdf the notion appears, however, the notation is no longer visible in visual mode. Does anyone know what is wrong? My first thought was it could be due to an update; however, I am fairly certain that I have not updated anything since.
When I am writing math equations in a markdown cell of a jupyter notebook, I casually put all of that in $ ... $. Today, I converted an .ipynb file to .tex, and realized most of these equations are converted into messy stuff in the output pdf. For instance, I realized it is converting all '$'s into '$'s.
This is an example of what has happened:
Jupyter Notebook markdown:
$ \nabla ^{2} f(x) = \frac{-1}{(x+1)^{2}} $
Tex Output:
\$ \nabla \^{}\{2\} f(x) = \frac{-1}{(x+1)^{2}} \$
Does anyone have any ideas why this is happening? Is there a better way to write down in-line math equations so that it is more compatible with LaTeX?
If you are eventually going to LaTeX version, the traditional advice is spelled out in minrk's comment from November 8 of 2012:
"The best solution for that right now would be to use 'raw' cells instead of markdown, and just type LaTeX as you would. Then use nbconvert to turn the ipynb to TeX (code, figures and all), and run latex to render that to PDF, etc. You don't get live-rendered TeX in the browser like you do with MathJax / Markdown, but you do still have TeX / code in one document."
The step where you are converting now is probably using nbconvert under the hood even if you aren't directly. (You may be using it directly since you tagged with 'nbconvert`.)
Alternatively, if you are going to LaTeX ultimately, you may want to use a code cell and use the LaTeX magic cell line at the start of that cell. See here and here about %%latex cell magic. (You'll note it is also mentioned among the StackOverflow thread I referenced earlier.) In regards to the %%latex cell magic, I suggest actually consulting the link that leads use in an example notebook in this post because it seems it has to be full-blown LaTeX code and not just simple equations that work easily elsewhere with just dollar signs bracketing them, i.e., MathJax.
I tried that option with your equation and when I output the notebook as LaTeX, I didn't see additional backslashes added. (I didn't however actually try rendering the LaTeX, and so I cannot address if all the cruft/boilerplate that Jupyter is adding causes any issues for downstream useability.)
I'm writing a slide deck using the Jupyter notebook and compiling it to slides using jupyter nbconvert FILENAME.ipynb --to=slides, which uses Reveal.js (if I understand correctly). I'm consequently writing the slide content in Markdown.
I'd like to have a slide with two columns, if possible. I cannot seem to make this work. Here is what I have tried:
The splitcell notebook extension suggested here. This does not work because (I think) it's for RISE, and I'm using Reveal.js. By "does not work" I mean that the split cells are treated as if I had not split them; it seems to have no effect.
The CSS suggestions suggested in many responses to this question. While several of the answers to that question successfully let me create two columns, none lets me use Markdown inside the columns, even though several of them explicitly say that they do. I have tried obeying all the suggestions in the comments as well, including blank lines and data-markdown. Perhaps those solutions work correctly when compiling from Markdown to slides through Reveal.js, but something is different about jupyter nbconvert?
The contributed notebook extension Split Cells (repo on GitHub) does exactly this.
This blog post shows Split Cells in action.
I have been using WxMaxima for my symbolic calculations for a while now. The good thing about WxMaxima is that you can get formatted outputs right in the program and then export them to LaTeX format with a click of the mouse.
Now I want to try the Jupyter/Ipython plus sympy for multiple reasons. I know how to use display(Math(r' some LaTeX math here ')) but what I want is to have the result/output of a cell in a nice mathematical form; something like the TraditionalForm[] command in Mathematica.
I would appreciate if you could help me know if/how I can get that right in a Jupyter notebook?
I think I found the proper solution and it is a sympy feature rather than Jupyter/IPython one. As explained here:
If all you want is the best pretty printing, use the init_printing() function. This will automatically enable the best printer available in your environment.
and
In the [Jupyter/]IPython notebook, it will use MathJax to render LATEX.
Then one can right click on the output and select Show Math As > Tex commands:
to get the LaTeX output.
P.S. A more proper formatting can be achieved via galgebra library. I will look into that and add it here later.
I am fairly new to doing report with R Sweave and know the very basic applications of Latex. And I have been asked to produce some statistical reports. The R markdown is great and simple, and by default it has really nice syntax frame and grey background and syntax highlights, however, it is quite limited in terms of other type setting, not really optimal when you want to produce lengthy reports. Then I am switching to use R Sweave in R studio.
I basically want the same after-effect similar to R markdown in the Sweave. What are the easiest ways to do it? I have previously read the following post discussing:
Sweave syntax highlighting in output. And I have tried reading those package pdf, but have no clues what they are talking about, as they seem to assume readers have prior knowledges about the rendering process.
i have checked them out, but I seem to get stuck in making it to work. Can anyone tell me step by step on how to set it up (such as what to include in preamble), if possible can you kindly upload a simple Rnw file with a demonstration?
Thank!
If you use knitr rather than Sweave, you'll get syntax highlighting. It's probably possible to do it in Sweave, but knitr makes it easier.
Go to your Tools | Global Options | Sweave menu (or the similar one in Project Options) in RStudio, and choose to Weave Rnw files using knitr.
The two systems are very similar, but knitr is generally preferable these days.
