### 13.13.6 The polar coordinates of a point: polar_coordinates

The polar_coordinates command finds the polar coordinates of a point.

- polar_coordinates takes one argument:
  P, a point.
- polar_coordinates(P) returns a list of the polar coordinates of P.

#### Example.

Input:

polar_coordinates(1 + i)

or:

polar_coordinates(point(1 + i))

or:

polar_coordinates([1,1])
