\erf etc
« on: October 21, 2016, 08:34:58 PM »
Definitely $erf$ should be printed upright, like $\sin$ and so on. Unfortunately LaTeX and standard packages do not know this command (macro) \erf. Neither does MathJax with standard extensions. But there is mechanism: I place* in the preamble of the LaTeX document
Code: [Select]
\newcommand{\erf}{\operatorname{erf}}and now I can use \erf. In Mathjax I place* on the page the same command, surrounded by dollar signs
Code: [Select]
$\newcommand{\erf}{\operatorname{erf}}$and again! $\newcommand{\erf}{\operatorname{erf}}$


*) Only once
