Text Formatting ⇒ enumerating equations/formulas

[denommenator]

Imagine this scenario: you are writing a homework assignment and many of the questions are multi-part, e.g. `find the derivative of the following functions,'

Now when it comes to listing the equations to differentiate I want to use an enumerate kind of format so that the functions are listed with a number before each one. The functions should be left justified, so I could just use enumerate and put dollar signs around each function (which is already tedious), but for readability, I also need all the equations to be displaystyle, they aren't inline text anyway.

How can I accomplish this? Is there an enumerate hack like the one for tabular where you can make a specific column in mathmode:

Code: Select all

\begin{tabular}{c | >{$}c <{$}} ... %First col textmode, 2nd col mathmode

Usually, displayed math environments are used for such a purpose, they are automatically numbered.

Code: Select all

\documentclass[leqno]{article}
\usepackage{mathtools}
\begin{document}
\begin{gather}
	a+b \\
	c+d\\
	\sum_{i}^{k}
\end{gather}
\end{document}

Hi,

and welcome to the forum!

There are further ways, such as align if you would like to have left alignment for the functions:

Code: Select all

\documentclass[leqno]{article}
\usepackage{mathtools}
\begin{document}
\begin{align}
  & a+b+c \\
  & c+d\\
  & \sum_{i}^{k}
\end{align}
\end{document}

More can be read in the amsmath manual. Or let us know, if something needs to be adjusted.
