How to use DeclareMathOperator in MathJax configuration file?

Question

I would like to declare some math operators in my local Mathjax configuration file, so that I could use them in every page.

I find that I could define command as described in the MathJax documentation, Defining TeX macros.

But I couldn't find any reference to use DeclareMathOperator in a configuration file? Any workaround?

Answer 1

I could achieve what you want with the configuration below:

MathJax.Hub.Config({
    TeX: {
        Macros: {
            sen: ["\\operatorname\{sen\}"],
            tg: ["\\operatorname\{tg\}"],
        },
    },
});
