I would like to create a new command for partial derivatives. I have something like this in mind:



newcommand{deriv}[2]{frac{partial #1}{partial #2}}


However, the partial commands are unfortunately not horizontally aligned, if I have e.g something like:



deriv{x^alpha}{t},


i.e. if argument #1 has a wider horizontal extent as argument #2. How can I enforce that the partial commands are always horizontally aligned?

    Like @JohnKormylo, I suspect that, when you say “in line”, you actually mean “vertically aligned” (like what you would get from, say, newcommand*{deriv}[2]{frac{partial #1}{partial #2hfill}}).

Set the numerator and denominator in a box of similar width and ensure they are both [l]eft-aligned. This is easily done using eqparbox and automated below to allow for any number of derivs (using a counter).



enter image description here



documentclass{article}

usepackage{eqparbox}

newcounter{derivcnt}
newcommand{deriv}[2]{%
stepcounter{derivcnt}%
frac
{eqmakebox[deriv-thederivcnt][l]{$partial #1$}}
{eqmakebox[deriv-thederivcnt][l]{$partial #2$}}}

begin{document}

[
deriv{a}{b} + deriv{abc}{d} - deriv{a}{bcd}
]

end{document}


Since this approach uses the .aux files to store the lengths of the boxes, multiple compilations are required with every change in the deriv content.
