Text Formatting ⇒ Pairs of Functions in enumerated List

[Cherrys]

Hello,

I'd like to use an indentation with two or more columns inside an enumeration, so that the two columns have the same indentation, and the left side corresponds to the right side. For example, I have a list of exercises, each requiring two functions f and g, and I'd like to have the f functions on the left, the g functions on the left, with every g function indented the same

What I did was this:

Code: Select all

\begin{multicols}{2}
  \begin{enumerate}
    \item $f(x)=(x-2)^2$
    \item $f(x)=x^n$
    \item $f(x)=\dfrac 13-\sqrt 2x$
    \item $f(x)=\dfrac{2x-7}{9x+3}$
  \end{enumerate}
  \begin{description}
    \item $g(x)=x^3$
    \item $g(x)=x^m$
    \item $g(x)=\dfrac{1}{1-x}$
    \item $g(x)=\dfrac{3x-2}{4x+1}$
  \end{description}
\end{multicols}

It works, but is not very practical when typing, because I have to define the g functions after I've defined every f functions. So if I have to change something to some functions, it's problematic to find it.

What I'd have liked would be to have something like:

Code: Select all

\begin{array}{ll}
  \begin{enumerate}
    \item first f function here & first g function here\\
    \item second f function here & second g function here\\
    \item etc
  \end{enumerate}
\end{array}

Is there any way to do something like that?

Thanks in advance for your help!

Would the usual equation numbering be an option or is the enumerated list a must?

Well, I'm coding exercises for students, and sometime, "enumerated" items are only texts, sometimes only equations, sometimes some of both. And in some cases, the indentation I'm trying to get is welcomed. So basically, I use enumerate because that way I get a single enumeration style for all my exercises. But if there's a more suitable alternative, it'd be great!

Thank for the welcome

In an enumerated list you can try to give each of the first functions f(x) a fixed width by using \makebox. Click on "Open writeLateX" in the head of the below code box to see the output instantly.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{mathtools}

\begin{document}
  \begin{enumerate}
    \item \makebox[10em][l]{$f(x)=(x-2)^2$} $g(x)=x^3$
    \item \makebox[10em][l]{$f(x)=x^n$} $g(x)=x^m$
    \item \makebox[10em][l]{$f(x)=\dfrac{1}{3}-\sqrt{2}x$} $g(x)=\dfrac{1}{1-x}$
    \item \makebox[10em][l]{$f(x)=\dfrac{2x-7}{9x+3}$} $g(x)=\dfrac{3x-2}{4x+1}$
  \end{enumerate}
\end{document}

Since you are preparing exercise sheets, you might be interested in packages and classes for exams and exercises.

The \makebox is perfect, thanks a lot!

As for the exercises/exams packages, I'm already using some
