MathJax Support works unreliable

[knorman]

Hello mdBook-Community!

I'm writing a technical documentation with many formulas. So far, it has all worked fine.
But now I have a problem with MathJax Support for only one formula. I try to type the following formula:

\\(t_n=max({t_{rap}}_n,{t_{tar}}_{n}+t_{mis}\frac{{t_{res}}_n}{t_{res}})\\)

On the rendered html-page I see this:

\(t_n=max({t_{rap}}n,{t{tar}}{n}+t{mis}\frac{{t_{res}}n}{t{res}})\)

But expected is this:

The formula works fine in DokuWiki with MathJax plugin but not in mdBook. So what is the problem? Or what I'm doing wrong?

Thank you!

I think you need to escape the underscores with a backslash. Otherwise, the markdown renderer is converting them to HTML italics. See #662.

This is the reason I put LaTeX between `$math$` or ```math blocks in my KaTeX handler. Don't have to worry about other passes interpreting LaTeX as Markdown that way.
