Math & Science ⇒ Bad math environment error

[pclarkUH3770]

I'm getting Bad math environment delimiter error for the entry below. It is also telling me that I have missing \endgroup inserted, <inserted text>. The output is typeset correctly, but the error is still showing??? Can anyone assist?


\documentclass[11pt]{article}
\newcommand{\Rho}{\mathrm{P}}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\begin{document}

\begin{equation}
\boldsymbol{\dot{\hat\rho}}=\[[\boldsymbol\omega\times]\boldsymbol{\hat\rho}_0}
\end{equation}

\end{document}

Hello and Welcome aboard
Your \[ (just after the equal sign) tries to start a new (displayed) math environment, but you're already in math mode.
The last closing brace has no partner, either.
BTW: you're defining \Rho, but you're using \rho. Since (La)TeX is case-sensitive, the definition of \Rho is superfluous at best.

Code: Select all

\documentclass[11pt]{article}
%\newcommand{\Rho}{\mathrm{P}}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\begin{document}

\begin{equation}
\boldsymbol{\dot{\hat\rho}}=[\boldsymbol\omega\times]\boldsymbol{\hat\rho}_0%}
\end{equation}

\end{document}

should work without error.
