I am looking for a notational shorthand to describe the pitch, roll, and yaw in an paper. Something akin to the $\vec{v} = (x,y,z)$ format for the position variables.
Is there a standard variable I would use for a vector, e.g. $\vec{k} = (\theta, \phi, \omega)$. Or would you just define a 6 vector $(x,y,z,\theta, \phi, \omega)$?
