LaTeX forum ⇒ Text Formatting ⇒ Create an array macro

[danielvelizv]

I need to create a macro with array environment that contents 3 columns and all its elements are \displaystyle ones, something I can use repeatedly throughout a document. Any idea to do that?

Here's an example:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

% in the preamble:
\usepackage{multienum}
\settowidth{\labelwidth}{\textbf{1.99)}}
...
\begin{multienumerate}
\everymath{\displaystyle}
\renewcommand{\labelenumi}{\addtocounter{multienumi}{1}\textbf{1.\arabic{multienumi})}}
\mitemxxx
   {$\int 2x - 3x^2\,dx$}
   {$\int 2x - 3x^2\,dx$}
   {$\int x^{3/2} + 2x + 1\,dx$}
\mitemxxx
   {$\int \frac{\sqrt{5x}}{5} + \frac{5}{\sqrt{5x}}\,dx$}
   {$\int (2t^2 - 1)^2\,dt$}
   {$\int 2 \sen x + 3 \cos x\,dx$}
\end{multienumerate}

Another idea:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass{article}
 
\usepackage{tasks}
 
\begin{document}
 
\begin{tasks}[item-format=\everymath{\displaystyle}](3)
   \task $\int 2x - 3x^2\,dx$
   \task $\int 2x - 3x^2\,dx$
   \task $\int x^{3/2} + 2x + 1\,dx$
   \task $\int \frac{\sqrt{5x}}{5} + \frac{5}{\sqrt{5x}}\,dx$ 
   \task $\int (2t^2 - 1)^2\,dt$
   \task $\int 2 \sin x + 3 \cos x\,dx$
\end{tasks}
 
\end{document}
