How to show math equations in general github s markdown not github s blog

Question

After investigating  I ve found mathjax can do this  But when I write some example in my markdown file  it doesn t show the correct equations   I have added this in the head of markdown file    lt script type  text javascript  src  http   cdn mathjax org mathjax latest MathJax js config default  gt  lt  script gt    And type the mathjax statement    E mc 2    x  1 2     frac -b  pm  sqrt b 2-4ac   2b      But github shows nothing for the math symbols  Please help me  thanks  Tell me how to show math symbols in github markdown pages

Mathcha is a sophisticated mathematics editor  but it can be used to render individual equations and save them as pure html  which you can then add to your documents as inline html OR you can save as SVG and insert as an image   https   www mathcha io

Markdown supports inline HTML   Inline HTML can be used for both quick and simple inline equations and  with and external tool  more complex rendering  Quick and Simple Inline For quick and simple inline items use HTML ampersand entity codes   An example that combines this idea with subscript text in markdown is  h  x     o x    1x  the code for which follows      h lt sub gt  amp theta  lt  sub gt  x     amp theta  lt sub gt o lt  sub gt  x    amp theta  lt sub gt 1 lt  sub gt x  HTML ampersand entity codes for common math symbols can be found here  Codes for Greek letters here  While this approach has limitations it works in practically all markdown and does not require any external libraries  Complex Scalable Inline Rendering with LaTeX and Codecogs If your needs are greater use an external LaTeX renderer like CodeCogs   Create an equation with CodeCogs editor   Choose svg for rendering and HTML for the embed code   Svg renders well on resize   HTML allows LaTeX to be easily read when you are looking at the source   Copy the embed code from the bottom of the page and paste it into your markdown   lt img src  quot https   latex codecogs com svg latex  Large amp space x  frac -b pm sqrt b 2-4ac   2a  quot  title  quot  Large x  frac -b pm sqrt b 2-4ac   2a  quot    gt    Expressed in markdown becomes    Large x  frac -b pm sqrt b 2-4ac   2a   https   latex codecogs com svg latex  Large amp space x  frac -b pm sqrt b 2-4ac   2a      This combines this answer and this answer  GitHub support only somtimes worked using the above raw html syntax for readable LaTeX for me   If the above does not work for you another option is to instead choose URL Encoded rendering and use that output to manually create a link like      Large x  frac -b pm sqrt b 2-4ac   2a   https   latex codecogs com svg latex x 3D 5Cfrac 7B-b 5Cpm 5Csqrt 7Bb 5E2-4ac 7D 7D 7B2a 7D   This manually incorporates LaTex in the alt image text and uses an encoded URL for rendering on GitHub  Multi-line Rendering If you need multi-line rendering check out this answer

While GitHub won t interpret the MathJax formulas  you can automatically generate a new Markdown document with the formulae replaced by images   I suggest you look at the GitHub app TeXify      GitHub App that looks in your pushes for files with extension   tex md and renders it s TeX expressions as SVG images   How it works  from the source repository       Whenever you push TeXify will run and seach for   tex md files in your last commit  For each one of those it ll run readme2tex which will take LaTeX expressions enclosed between dollar signs  convert it to plain SVG images  and then save the output into a  md extension file  That means that a file named README tex md will be processed and the output will be saved as README md   After that  the output file and the new SVG images are then commited and pushed back to your repo

But github show nothing for the math symbols  please help me  thanks    GitHub markdown parsing is performed by the SunDown  ex libUpSkirt  library   The motto of the library is  Standards compliant  fast  secure markdown processing library in C   The important word being  secure  there  considering your question       Indeed  allowing javascript to be executed would be a bit off of the MarkDown standard text-to-HTML contract   Moreover  everything that looks like a HTML tag is either escaped or stripped out      Tell me how to show math symbols in general github markdown    Your best bet would be to find a website similar to yuml me which can generate on-the-fly images from by parsing the provided URL querystring   Update  I ve found some sites providing users with such service  codedogs com  no longer seems to support embedding  or iTex2Img  You may want to try them out  Of course  others may exist and some Google-fu will help you find them   given the following markdown syntax    equation  http   www sciweavers org tex2img php eq 1 2Bsin 28mc 5E2 29 amp bc White amp fc Black amp im jpg amp fs 12 amp ff arev amp edit     it will display the following image  equation http   www sciweavers org tex2img php eq 1 2Bsin 28mc 5E2 29 amp bc White amp fc Black amp im jpg amp fs 12 amp ff arev amp edit   Note  In order for the image to be properly displayed  you ll have to ensure the querystring part of the url is percent encoded  You can easily find online tools to help you with that task  such as www url-encode-decode com

If just wanted to show math in the browser for yourself  you could try the Chrome extension GitHub with MathJax  It s quite convenient

A  quot quick and dirty quot  solution is to maintain a standard  md file using standard TeX equations  e g   README md  When you are satisfied  pass the entire file through Pandoc to convert from standard Markdown  to Markdown  Github flavour   and copy the output to README md  You can do this online for a quick turnaround  or install configure Pandoc locally

There is good solution for your problem - use TeXify github plugin  mentioned by Tom Hale answer - but I developed his answer in given link below  - more details about this github plugin and explanation why this is good approach you can find in that answer

I use the below mentioned process to convert equations to markdown  This works very well for me  Its very simple    Let s say  I want to represent matrix multiplication equation  Step 1   Get the script for your formulae from here - https   csrgxtu github io 2015 03 20 Writing-Mathematic-Fomulars-in-Markdown   My example  I wanted to represent Z i j  X i k    Y k  j   k 1 to n into a summation formulae     Referencing the website  the script needed was     Z i j  sum  k 1   10  X i k   Y k j  Step 2   Use URL encoder - https   www urlencoder org  to convert the script to a valid url My example    Step 3   Use this website to generate the image by copy-pasting the output from Step 2 in the  eq  request parameter - http   www sciweavers org tex2img php eq  lt b gt  lt i gt paste-output-here lt  i gt  lt  b gt  amp bc White amp fc Black amp im jpg amp fs 12 amp ff arev amp edit      - My example   http   www sciweavers org tex2img php eq Z i j  sum  k 1   10  20X i k 20  20Y k j amp bc White amp fc Black amp im jpg amp fs 12 amp ff arev amp edit    Step 4   Reference image using markdown syntax -   alt text  enter url here      - Copy this in your markdown and you are good to go     Z i j  X i k    Y k  j   k 1 to n  http   www sciweavers org tex2img php eq Z i j 3D 5Csum  7Bi 3D1 7D 5E 7B10 7D 20X i k 20 2A 20Y k j amp bc White amp fc Black amp im jpg amp fs 12 amp ff arev amp edit    Image below is the output of markdown  Hurray

Regarding tex image conversion  the tool LaTeXiT produces much higher quality output  I believe it is standard in most TeX distributions but you can certainly find it online if you don t already have it  All you need to do is put it in the TeX  drag the image to your desktop  then drag from your desktop to an image hosting site  I use imgur

One other work-around is to use jupyter notebooks and use the markdown mode in cells to render equations    Basic stuff seems to work perfectly  like centered equations   begin equation       end equation    or inline equations     sum   forall i  x i  2       Although  one of the functions that I really wanted did not render at all in github was  mbox    which was a bummer  But  all in all this has been the most successful way of rendering equations on github
