Math & Science ⇒ Aligning equations

[astrak]

Hello!
I would like ask you how to set some equation which is written in more lines to the left side.

I should use $math$ but there is problem that a first equation is a bit more on right side (first white space in the paragraph).
When I use align, array, multline, ... all equations are centered in the midle of page.

Thank you very much!

You could set the fleqn option to the document class and specify \mathindent to be zero, such as:

Code: Select all

\documentclass[fleqn]{article}
\usepackage{amsmath}
\setlength{\mathindent}{0pt}

Thank you Stefan!
Unfortunately fleqn as a document class doesn't work in TeX Works, but when I use \begin{flalign*} it works very well.

So thank you for recomandation!

fleqn is an option to classes and to amsmath, not a class. It works for me with TeXworks exactly in this way.

Yes, flalign works too, using & to push the formula to the left, however fleqn works document wide also for simple equations.

When I use fleqn as an option to class - it looks like that:

Code: Select all

\documentclass[fleqn][a4paper,11pt]{article}

\usepackage[czech]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage{graphicx}
\usepackage{hyperref}
\usepackage{amsmath}
\usepackage{amsfonts}

\setlength{\mathindent}{0pt}

\begin{document}
...

But with TexWorks it doesn't work - error message is:

! LaTeX Error: File `.cls' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: cls)

Enter file name:

Hallo,

the syntax of the first line is not correct. It should be:

Code: Select all

\documentclass[fleqn,a4paper,11pt]{article}

Now it works with no problems
