Physics

physics package allows you to quickly typeset frequently used mathematical formulas in Physics. For more detail about how to use it, the audience may refer to manual which comes with $\TeX$ distribution. Bellow is an example of using the package.

\documentclass{article} \usepackage{physics} \begin{document} This is an example of write math formulas which are frequently use by Physicists. \begin{enumerate} \item Automatic bracing \begin{eqnarray} (a+b), \qty\big[a+b], \qty\Big|a+b|, \qty\bigg{a+b}, \qty\Bigg(a+b)\\ \abs{x},\norm{x},\eval{x}_{0}^{+\infty},\order{x^2},\comm{A}{B},\acomm{A}{B},\pb{A}{B}\\ \end{eqnarray} \item Vector Notation \begin{equation} \vb{a},\vb*{a},\va{a},\va*{a},\vu{a},\vu*{a},a\vdot b,a\cross b,\grad,\grad{\phi},\div,\div{\phi},\curl,\curl{a},\laplacian,\laplacian{\psi} \end{equation} \item Derivatives \begin{eqnarray} \dd,\dd x,\dv{x},\dv{f}{x},\dv*{f}{x},\pdv{x},\pdv{f}{x},\pdv[n]{f}{x},\pdv{f}{x}{y},\var{F},\fdv{g},\fdv{F}{g},\fdv{V}(E-TS) \end{eqnarray} \end{enumerate} \end{document}

If you require more symbols or notation that cannot be found in the above package, you can use comprehensive AMS package bundle including amsmath, amssymb and amsthm.
