# [Tex/LaTex] How to write partial differential equation (Ex. dQ/dt=ds/dt) with real partial derivative signs

equations

I would like to make a partial differential equation by using the following notation:

dQ/dt

(without / but with a real numerator and denomenator). Earlier today I got help from this page on how to u_t, but now I also have to write it like dQ/dt. I understand how it can be done by using dollarsigns and fractions, but is it possible to do it using

$$....$$


so that it can be on separate lines and using math-style?

#### Best Answer

You said partial differential equation:

\documentclass{article}
\begin{document}
$$\frac{\partial Q}{\partial t} = \frac{\partial s}{\partial t}$$
\end{document}


now using physics package, extra goodies (bonus):

\documentclass{article}
\usepackage{physics}
\begin{document}
$\dv{Q}{t} = \dv{s}{t} \quad \dv[n]{Q}{t} = \dv[n]{s}{t} \quad \pdv{Q}{t} = \pdv{s}{t} \quad \pdv[n]{Q}{t} = \pdv[n]{s}{t} \quad \pdv{Q}{x}{t} = \pdv{s}{x}{t} \quad$
$\fdv{F}{g}$
\end{document}
