Math & Science ⇒ Suppress new Line after Equation

[Singularity]

Hello.

I would like have the period at the end of a sentence which ends with and equation to immediately follow the equation, not on a new line. But I don't want to include the period in the equation (which just doesn't seem right - the period is not part of the equation).

In other words, I want the period in this code to appear right after the equation, instead of where it appears (circled in the graphic):

Code: Select all

\documentclass[12pt,fleqn,reqno]{article}
\begin{document}
We do all kinds of manipulations which you guys in latex-community don't want to read about, and then we get

\begin{equation}
	\ddot{u}_n=k(u_{n-1}-2u_{n}+u_{n+1})
\label{theeEquation}
\end{equation}.

\end{document}

Thanks for your help.

P.S. If putting the period inside the equation line is the only, or appropriate, way to do this, what about if you wanted something else on the same line?

Hi,

the equation environment is a displayed environment, with spacing before and after. If you wish to have a dot within that displayed environment, put the dot inside. It's logical from the typesetting view. If you don't want to mix text and math, don't embed a displayed formula in a sentence. If you would like, you could use inline math with \( ... \) or $...$.

Well, it seems like the standard is to write math as grammatically correct sentences (says my thesis adviser and a Latex tips site). Therefore, it needs a period where there should be one. If I want to write an equation which should stand out, is too big to use the inline math, or needs to be numbered, I still need the period.

Is the standard just to put the period into the equation environment? That just seems inconsistent with what LATEX I've learned (note that I am a newbie).

I want to write correctly because I have already been corrected as to how to type inline numbers (e.g. "there are 5 of them" should be written as "there are $5$ of them").

Thanks, Stefan.

No problem, the best is with amsmath and \text:

Code: Select all

\usepackage{amsmath}
...
\begin{equation}
  \ddot{u}_n=k(u_{n-1}-2u_{n}+u_{n+1}) \text{ and that's all}.
  \label{theeEquation}
\end{equation}

You can also write

Code: Select all

\ddot{u}_n=k(u_{n-1}-2u_{n}+u_{n+1}) \text{.}

if you like to have the correct text font period.

It seems most people just put the period in the equation (some examples I just see online). I'll use \text when necessary to include something.
Thanks.
