# flalign* still maintaining indent - caused by \text{}?

The goal is to align all of the text that spans more than one line with the equal sign. It appears that if I use

\usepackage{amsmath}


in my preamble and then use

align*


it will align with the equal sign, but has a left indent I don't want (I want my text flush-left). I have found

flalign*


(again using

\usepackage{amsmath}


in the preamble), but it's not working as the examples I have found work - the text is not flush left. I wonder if it has something to do with \text?

Here is the example I found that WORKS:

\documentclass{article}
\usepackage{showframe}
\usepackage{amsmath}
\begin{document}
\begin{flalign*}
\cos\theta_1 \cos\theta_2-\sin\theta_1\sin\theta_2 &= \cos(\theta_1 +\theta_2) &\\
\sin\theta_1 \cos\theta_2 + \cos\theta_1 \sin\theta_2 &= \sin(\theta_1+\theta_2) &
\end{flalign*}
\end{document}


Now, what I really want to be flush-left that ISN'T WORKING:

\documentclass{article}
\usepackage{showframe}
\usepackage{amsmath}
\begin{document}
\begin{flalign*}
C_C = &\text{ those indices from the set of $k$ where $V$ and $W$ are both observed (i.e.} \\
&\text{ completers")}
\end{flalign*}
\end{document}


Again, I can't post an image of my results.

I would like the C_C to be completely flush left. Does it have something to do with \text in my expression, which wasn't used in the example I found that worked?

Tip: As new user without image posting privileges simply include the image as normal and remove the ! in front of it to turn it into a link. A moderator or another user with edit privileges can then reinsert the ! to turn it into an image again. –  Torbjørn T. Sep 9 '12 at 17:08
@TorbjørnT. Thank you! –  Meg Sep 11 '12 at 12:07

use

\usepackage[fleqn]{amsmath}
\mathindent=0pt

The working example has ampersands at the end of each line, whereas yours does not. To get the C_C flush left, try this.

\documentclass{article}
\usepackage[a4paper]{geometry}
\usepackage{amsmath}
\begin{document}
\noindent The quick brown fox jumps over the lazy dog.
\begin{flalign*}
C_C = &\text{ those indices from the set of $k$ for which $V$ and $W$ are both observed (i.e.} &\\
&\text{completers'')}&
\end{flalign*}
\end{document}

Ahhh yes. Thank you! I think I didn't notice them because of using align and not needing them at the end of the lines in that case. Thank you for being more observant than I! –  Meg Sep 11 '12 at 12:14
