I'm trying to typeset the equation for the dot product like this (using the physics package).
$$ \va{A} \dot \va{B} = abs{A}abs{B}\cos{\theta}$$
However, LaTeX keeps throwing this:
./AP Physics Notes.tex:29: Missing } inserted. [$$ \va{A} \dot \va]
./AP Physics Notes.tex:29: Missing } inserted. [$$ \va{A} \dot \va]
./AP Physics Notes.tex:29: Extra }, or forgotten $. [$$ \va{A} \dot \va]
./AP Physics Notes.tex:29: Extra }, or forgotten $. [$$ \va{A} \dot \va]
Not sure what I'm doing wrong...any help would be appreciated! Thanks so much.
\documentclass{...}
and ending with\end{document}
.$$....$$
please. Try\[ .... \]
around it\cdot
not\dot
