Writing mathematical equation in jupyter notebook in a markdown (.md) file - jupyter-notebook

I have written a document in the jupyter notebook as a markdown (.md) file. The document contains some mathematical equation which I have written inside $$ equation $$, for example,
$$c = \sqrt{a^2 + b^2}$$
Now, when I push the .md file in the Gitlab, my equations are appearing in the latex format, like
$$c = \sqrt{a^2 + b^2}$$
The file was okay when I did the print preview but in the GitLab the equations are appearing inside $$...$$.
Could you pls help me to resolve the issue?
Thanks!!

I have found a solution to resolve the issue. Most of the solutions are mentioned in the below link in the math section
https://docs.gitlab.com/ee/user/markdown.html
To summarise
This math is inline $`a^2+b^2=c^2`$
This is on a separate line
```math
a^2+b^2=c^2
```
Separate line with equation number
```math
\tag{1} a^2+b^2=c^2
```
Now, I am trying to find how to add \label{} in the equation.

r markdown inline equation newline issue

I am using R markdown with rmarkdown::render(). The problem I am having is that all inline latex equations gets displayed in a new line in the resulting html document.
For example, the .Rmd file containing the following:
numeric observations $y_1,\dots y_T$ up to some time $T$
turns out line breaks before y_1 and before T.
Has anybody had this problem and/or knows how to fix it?
Thank you in advance,
Giovanni

R notebook inline latex output

I have a simple LaTex code in my R notebook as
$y=\frac{(x-\mu)}{(max-min)}$
When I hover on the code, I see the output and also when I knit to HTML. However, how do I see the rendered output within the .RMD file?
I know this can be done because once I accidentally hit something on the keyboard and I was able to see the rendered LaTeX output within the .RMD file itself. I just do not know what I hit and I am not able to reproduce that behavior. I was not able to find in documentation as well.
Display equations (surrounded with $$) preview as a chunk result rather than a popup, as inline equations ($) do.
$$y=\frac{(x-\mu)}{(max-min)}$$
However, note that $$ will print the math in its own paragraph/div while $ produces inline output. AFAIK, there is no way to have inline equations preview without hovering over them.

R Markdown: displaying summation command in PDF output

I'm brand new to R, as in my class just began two days ago. In our first assignment we are to show our work and answers, which are written in R Markdown (inside R Studio) and then output in PDF.
On one question we are asked to display the quadratic equation. I know the command, which I figured out is $$ x=\frac{ -b \pm \sqrt{ b^2 - 4ac} }{2a} $$.
After I Knit the file to PDF the equation shows up all nice and pretty. However, I cannot figure out how to also get the command to also display to show my work. If I prefix the command with an asterisk, backslash, hashtag, etc., after I knit the file it shows the prefix and then just displays the quadratic equation but not the command.
I'd ask my prof, but he actually suggested we try Stack Overflow with questions in the syllabus (haha!), then referred to himself as a "facilitator more than a teacher". Hmmm. So here I am.
One option is to insert a chunk with your equation:
```
$$ x=\frac{ -b \pm \sqrt{ b^2 - 4ac} }{2a} $$.
```

equation not well formatted using markdownToHTML

Having this code in a test.md file
$$
\begin{aligned}
20x 1 \leqt 70
\end{aligned}
$$
When I use RStudio button Preview Html the equation is well formatted using Mathjax.
But when I try to do it using markdownToHTML function:
for example
markdownToHTML('test.md', 'test.html'),
the equation is not formatted.
The bug is due to the extra blank line after my equation( I can't remove it because the equation is generated using an R chunk and the cat command)
Does Rstudio does any post-processing on .md files to remove blank lines between $$ ?
For RStudio, we actually have our own version of the markdown package embedded which does the conversion from .md to .html. I tried your scenario and was able to reproduce as well. I recommend reporting this to Jeff Horner to see if there is a bug here that he can fix:

LaTeX Page Size --- how do I produce a page that is "just big enough"?

I was learning about using the command line version of latex today, and I was experimenting with outputting .tex to .dvi, and then .dvi to .png.
The problem is, I have a simple .tex document which contains some math. The goal is to eventually produce a png form of the equation. But when I run:
$ latex -output-format=dvi test.tex
$ dvipng test.dvi
I get test1.png that is shaped like a regular letter-sized page. I only want an image that is as big as the equation needs to be. I'm sure I'm missing something obvious, but I can't figure it out!
Is there a command line option for either latex or dvipng to specify that the output file should only be set on a page as large as needed to render the equation?
Here's my example test.tex:
\documentclass{article}
\begin{document}
The solution to $\sqrt{x} = 5$ is $x=25$.
\end{document}
Thanks!
Try
dvipng -T tight filename
EDIT: As Mr tur1ing points out, you'll also want \pagestyle{empty} to avoid having a page number muck up the works.
Try mathurl and Roger's Online Equation Editor. There probably several other such sites.
