Left align (to the page) displayed math
You can use flalign
from the amsmath
package:
Note:
- The
showframe
package was used just to be able to see where the text is relative to the page margins.
Code:
\documentclass{article}
\usepackage{showframe}
\usepackage{amsmath}
\begin{document}
\begin{flalign*}
e & = mc ^2 &\\% Note the trailing & which is required to equations to the left
F & = ma
\end{flalign*}
\end{document}
Alternatively, if you want all equations left aligned, you can use the package option fleqn
as in \documentclass[fleqn]{article}
which will align them towards the left. The indentation is controlled by \mathindent
, so you could use \setlength{\mathindent}{0pt}
if you wanted to eliminate that.
Code:
\documentclass[fleqn]{article}
\usepackage{showframe}
\usepackage{amsmath}
\setlength{\mathindent}{0pt}
\begin{document}
\begin{align*}
e & = mc ^2 \\
F & = ma
\end{align*}
\end{document}
It seems that the current accepted answer doesn't exactly answer the question (OP stated either $$
or \[
and not the align
environment because he already found a solution for that).
Here is a solution with \[ ... \]
(doesn't work with $$...$$
though):
\documentclass[fleqn]{article}
\setlength{\mathindent}{0pt}
\begin{document}
\noindent Here is some left-aligned math:
\[x^2+1\]
\end{document}
