We can express all kinds of functions in ,polar, coordinates, but some are more suitable for them than others. For example, the vertical and horizontal lines in the first graph below are what we could call "native" to the rectilinear (made up of lines and 90˚ ,angles,) Cartesian coordinate system. That's why their equations are so simple.
