Math color in my calculator mimic

Question

All,

I'm working on another calculator screen. This will produce what I have thus far. Note the line in red, with a single mu character in red. I need that line to read:

\mu:\ne\mu_0  <\mu_0  >\mu_0

I also need to select one of the three, put a black background and type the characters in white.

Any suggestions?

Answer 1

Below are two of the options you are looking for. Here I have defined the \WhiteText macro which places the text within a black box. This also adjusts the horizontal separation of the black box so that it does not result in any shifting of the text.

Further Enhancements:

• It may be preferable to define a single \mymumu macro that accepts a parameter (0,1,2,3) which defines which of the three terms are to use the \WhiteText macro.

Code:

\documentclass{article}
\usepackage{amsmath}
\usepackage{tikz}

\newcommand*{\WhiteText}[1]{%
    \colorbox{black}{\kern-\fboxsep\textcolor{white}{#1}\kern-\fboxsep}%
}%

\usepackage{booktabs}
\usepackage{xparse}
\newcommand\tsurd{\ensuremath{\sqrt{\phantom{i}}}}
\newcommand\txbar{\ensuremath{\overline{\text{x}}}}
\newcommand\sumx{\ensuremath{\Sigma{\text{x}}}}
\newcommand\sumxsq{\ensuremath{\Sigma{\text{x}}^2}}
\newcommand\sigmax{\ensuremath{\sigma{\text{x}}}}
\newcommand\muzero{\ensuremath{\mu_0}}
\newcommand\muzerone{\ensuremath{\ne\mu_0}}
\newcommand\mymu{\ensuremath{\color{red}{\mu}}}

\newcommand\mymumuA{\ensuremath{\color{red}\mu:\ne\mu_0 <\mu_0 >\mu_0}}
\newcommand\mymumuB{\ensuremath{\color{red}\mu:\ne\mu_0 < \WhiteText{$\mu_0$} >\mu_0}}
