I am trying to typeset a vector with i-hat and j-hat components:
\documentclass{article}
\usepackage{amsmath}
\usepackage{mathtools}
\newcommand{\ihat}{\mathbf {\hat \imath}}
\newcommand{\jhat}{\mathbf {\hat \jmath}}
\newcommand{\vect}[1]{\mathbf #1}
\begin{document}
\begin{align}
\vect{F} &= 3\ihat + 4\jhat
\end{align}
\end{document}
However, \imath
and \jmath
will always be italicized, no matter what modifiers I apply \mathbf
, \mathrm
, etc.
How do I make \imath
and \jmath
bold and upright?
Best Answer
For bold and upright, you could use the regular text-version of
\imath
and\jmath
, which are\i
and\j
:Additionally, if you want the
\hat
to be bold as well, then use\boldsymbol
.
