Relação com coordenadas cartesianas:

$\displaystyle {\color{myblue}x \, = \, \rho \, {\rm cos} \, \theta} \quad$ $\textstyle ,$ $\displaystyle \quad {\color{mypurple}\hat\rho\, =\, \hat{x} \,{\rm cos}\, \theta \,+\, \hat{y}\, {\rm sen}\, \theta }$  
$\displaystyle {\color{myblue}y\, = \,\rho \,{\rm sen}\, \theta} \quad$ $\textstyle ,$ $\displaystyle \quad {\color{mypurple}\hat\theta\, =\, -\, \hat{x} \,{\rm sen}\, \theta \,+\, \hat{y}\, {\rm cos}\, \theta}$  
$\displaystyle {\color{myblue}z \,= \,z} \quad \quad \; \quad$ $\textstyle ,$ $\displaystyle \quad {\color{mypurple}\hat{z}\, = \, \hat{z} }$
