What is the difference in the "uniqueness" of the representations of Cartesian coordinates and in polar coordinates? :confused: Also, what is the non-uniqueness?

Take an example:

The point with unique cartesian coordinates (1,0) has many possible polar coordinates, such as [itex](1,0), (1, 2\pi), (1,4\pi)[/itex].

Non-uniqueness is having multiple expressions for the same point.
