Math & Science ⇒ Vertical line and a Fraction

[rayman]

hello! I have problems with finding a command which would place a vertical line next to a fraction. In the attachment is the thing I am looking for

Thank you!

There are several commands for manual adjustment of this vertical bar. See example below.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{mathtools}   % loads »amsmath«

\begin{document}
  \begin{alignat*}{2}
    \phi_\ast\frac{d}{dt}\bigg|_0 &= \frac{d\phi^\mu(t)}{dt}\bigg|_0\,\frac{\partial}{\partial g^\mu}\bigg|_e &&= X|_e \\
    \phi_\ast\frac{d}{dt}\bigg|_t &= \frac{d\phi^\mu(t)}{dt}\bigg|_t\,\frac{\partial}{\partial g^\mu}\bigg|_g &&= X|_g
  \end{alignat*}
\end{document}

See the »Math mode« document for further reading.


Best regards and welcome to the board
