Align $\displaystyle\frac{dx(t)}{dt}$

Question

In $\displaystyle\frac{dx(t)}{dt}$. Is it possible to align $dx(t)$ with $dt$? Well, as I write it, it looks wrong.

Answer 1

You can use \hfill in the denominator of the fraction to force left alignment if that is what you are looking for. You could also typeset the term a bit more balanced by having the x(t) outside the fraction.

\documentclass{article}
\begin{document}
$\displaystyle\frac{dx(t)}{dt\hfill}$
$\displaystyle\frac{d}{dt}\big(x(t)\big)$
\end{document}

EDIT: As @Zarko says, you can save yourself the \displaystyle command by using \dfrac{}{} from the mathtools package.
