amsmathhorizontal alignment
I am using LaTeXila in Ubuntu and I want to center my math equation so I have this written:
$\[ 2^{10} \]$
But when I try to compile into PDF, it outputs the error:
Bad math environment delimeter
How do I get it to center math text properly? Thanks
You can use flalign from the amsmath package:
showframe package was used just to be able to see where the text is relative to the page margins.\documentclass{article}
\usepackage{showframe}
\usepackage{amsmath}
\begin{document}
\begin{flalign*}
e & = mc ^2 &\\% Note the trailing & which is required to equations to the left
F & = ma
\end{flalign*}
\end{document}
Alternatively, if you want all equations left aligned, you can use the package option fleqn as in \documentclass[fleqn]{article} which will align them towards the left. The indentation is controlled by \mathindent, so you could use \setlength{\mathindent}{0pt} if you wanted to eliminate that.
\documentclass[fleqn]{article}
\usepackage{showframe}
\usepackage{amsmath}
\setlength{\mathindent}{0pt}
\begin{document}
\begin{align*}
e & = mc ^2 \\
F & = ma
\end{align*}
\end{document}
Some suggestions:
In an equation environment, you're automatically in (display-) math mode. No point in entering math-mode twice. (As you've found out the hard way, one can't re-enter math mode if one is already in math mode...)
Don't neglect to use subscripts as needed. (I kept V_o, but I have a hunch that V_0 might be more appropriate.)
For multiplication and division, consider using \cdot and / instead of \ast and \div.
To typeset physical quantities, I recommend loading the siunitx package and writing \SI{50}{\micro\ampere} rather than 50\(\mu\)A.
\documentclass{article}
\usepackage{siunitx}
\begin{document}
\begin{itemize} % or 'enumerate'
\item $V_o$ is calculated as shown:
\begin{equation}
V_o = (1 + R_1 / R_2) + (I_{\textnormal{adj}} \cdot R_2)
\end{equation}
Because $I_{\textnormal{adj}}$ typically is \SI{50}{\micro\ampere}, it
is negligible in most applications.
\end{itemize} % or 'enumerate'
\end{document}
Best Answer
will give you inline math, i.e., a formula in the middle of the text.
will give you display math, i.e., a formula separated from the text, and centered.
