Symbol | Hat |
---|---|
Type of symbol | Mathematics |
Package (requirement) | No |
Argument | Yes, x |
Latex command | \hat{x} |
Example | \hat{o} → ô |
Not only mathematically, but hat symbol is also used in different languages. For this, there is by default \hat{}
a command in latex. For example, you can see the use of this symbol in the case of a unit vector.
\documentclass{article}
\begin{document}
$$ \hat{r} = \frac{\vec{r}}{\mid \vec{r} \mid} $$
$$ \hat{v} = \frac{\textbf{v}}{\mid \textbf{v} \mid} $$
$$ \hat{i}, \hat{j}, \hat{k} $$
\end{document}
Output :
Since the unit vector is a topic of physics. So, \vu{arg}
macros are being created for the unit vector in the physics package. This \vu{arg}
command is considered to be the short form of the \vectorunit
command.
\documentclass{article}
\usepackage{physics}
\begin{document}
$$ \vu{r} = \cos\theta \vu{i} + \sin\theta \vu{j} $$
$$ \vu{r}_x = \cos\theta \vu{i}, \vu{r}_y = \sin\theta \vu{j} $$
$$ \abs{\vu{r}} = \sqrt{\cos^2\theta + \sin^2\theta} = 1 $$
$$ \left ( \hat{i},\hat{j},\hat{k} \right ) $$
\end{document}
Output :
Center the hat symbol above the letter with subscript
You must write the syntax correctly to use hat symbols and subscripts together. If you write like this \hat{U_i}
, the hat symbol will not be in the center of the letter in the output. To print the hat symbol in the center you should write it like this \hat{U}_i
. Same format for superscript. take a look
\documentclass{article}
\usepackage{MnSymbol}
\begin{document}
$$ \verb|\hat{U_i}|\longrightarrow \hat{U_i} $$
$$ \verb|\hat{U}_i|\longrightarrow \hat{U}_i $$
$$ \verb|\hat{M^n}|\longrightarrow \hat{M^n} $$
$$ \verb|\hat{M}_n|\longrightarrow \hat{M}^n $$
\end{document}
