[Tex/LaTex] How to write the symbol >

symbols

I had a look at the symbols list, and it is written that the input text ">" should be rendered as ">". In my document, however, it is rendered as "¿".

How do I write a normal ">"?

Very likely you are using the old OT1 encoding:

\documentclass{article}
\begin{document}
<Hello> \textless world\textgreater
\end{document}

The example also shows how to typeset < and > by using \textless or \textgreater.

The issue is resolved with the T1 font encoding:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}% optional
\begin{document}
<Hello> \textless world\textgreater
\end{document}

Example for `siunitx` and pdfLaTeX

If lualatex or pdflatex cannot be used, then the symbol can be included as graphics. The graphics is generated by:

% franc.tex
\nofiles
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontspec{FreeSerif.otf}
^^^^20a3
\end{document}

It is compiled via:

$ lualatex franc
$ pdfcrop franc

Then franc-crop.pdf can be used as image for pdfLaTeX:

\documentclass{article}
\usepackage{graphicx}
\usepackage{siunitx}
\DeclareRobustCommand*{\myfranc}{\includegraphics[scale=.1]{franc}}
\DeclareSIUnit{\franc}{\myfranc}

\begin{document}
\SI{123.45}{\franc}
\end{document}

If you are using lualatex or xelatex, then the font can be used directly, e.g.:

\DeclareRobustCommand*{\myfranc}{%
  \begingroup
    \fontspec{FreeSerif.otf}%
    ^^^^20a3%
  \endgroup
}

[Tex/LaTex] How to write relative permittivity in text

LaTeX provides, as any new user finds out, support for greek letters in math mode, with macro names that are spelled out: \alpha, \beta, \delta, etc.

Unfortunately, the default appearance of \epsilon is

which is not what the OP was seeking.

However, one finds on p.43 of Lamport's LaTeX User Guide that several greek letters have variants that are available through standard LaTeX. Namely, \varepsilon, \vartheta, \varpi, \varsigma, \varphi.

A comparison of the standard versus the variant forms is given below:

We find that, indeed, \varepsilon is the desired form of the OP.

Other details about the OP's question were the inclusion of subscripts These are done in math mode, with the subscript following a _ character; however, only a single character is typically absorbed into the subscript (e.g., \varepsilon_0), so that longer subscripts should be grouped in braces as \varepsilon_{xy}. In the case of one of the OP's examples, an upright r was requested as the subscript. If one used \varepsilon_r, the r would be in standard math mode, which is italic

However, one can ask for upright math mode by way of \mathrm{} (math-roman), which already comes pre-grouped, so that \varepsilon_\mathrm{r} yields

The only final thing to mention, which is very introductory, is that inline math (so-called \textstyle) is accessed by way of dollar delimiters $...$ , or in many ways more preferably, $...$ delimiters. If one wants the math on a line by itself (so-called \displaystyle), with no efforts to compress the expression into a single row height, then \[...\] delimiters are used, or else one of the many LaTeX math environments such as equation or the amsmath.sty environments in the align family.

Thus, to achieve the OP's request, I provide the following MWE:

\documentclass{article}
\begin{document}
$\varepsilon_\mathrm{r}$ and $\varepsilon_0$ are inline expressions
\end{document}
