General ⇒ Inline latex symbols

[Philosophaie]

I would like to be able to use latex symbols in the same line along with the flow of the line not returned to the next line.
How do I do that without making the whole paragraph a "gather*"?

Code: Select all

\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}
It is based on the \begin{??}R_{ecl}\end{??} distance with two angle to define position: Ecliptic Longitude, \begin{??}\lambda\end{??}, and Ecliptic Latitude, \begin{??}\beta\end{??}.  \begin{??}\lambda\end{??} exists on the Ecliptic Plane starting from the Vernal Equinox Line and \begin{??}\beta\end{??} is the angle above or below the Ecliptic Plane (Northward positive, Southward negative, never greater than +/-90 Degrees).
\end{document}

You could write it in the high-level LaTeX way

Code: Select all

It is based on the \( R_{ecl} \) distance 

or in the low-level TeX way (shorter, but the above is more abstract and one sees begin and end in a math formula scattered text):

Code: Select all

It is based on the $R_{ecl}$ distance
