setting the counter of equations to 1 in each post

[עופר מגד‎]

Does anyone know how to reset the counter of equations in the beginning of each post? Apparently, it continues to count-up when moving from one post to another. In other words, how do I implement the command \setcounter{equation}{0} within Mathjax? BTW, I am using the blogger dynamic template.

Thanks.

Hi,

This is currently not supported. I think the following should work

        <script type="text/x-mathjax-config">

            MathJax.Hub.Register.StartupHook("TeX AMSmath Ready", function() {

                MathJax.InputJax.TeX.Definitions.Add({

                    macros: {

                    setCounter: "setCounter"

                    }

                }, null, true);

                MathJax.InputJax.TeX.Parse.Augment({

                    setCounter: function(name) {

                    var num =  parseInt(this.GetArgument(name));

                    MathJax.Extension["TeX/AMSmath"].number = num;

                    }

                });

            });

        </script>

BEFORE MathJax.js is loaded. (Or add the contents to an existing configuration script.

Then you can use \setcounter{0} to reset (or set to any number).

Here's a live demo and a GIst.

Best wishes,

Peter

Thank you very much for your suggestion. 

I'll try it.

Works great Peter! Thanks for sharing. I used the code in the Gist script in an R/Shiny app that renders rmarkdown files. Equation numbering would start on the file/page was opened first which is probably not what you want. The only change I had to make was to use autoNumber: "all" rather than autoNumber: "AMS". Thanks again.
