Suggest methods (other than Cartesian Coordinates) of describing the location of points on a plane.

There are two alternatives: (i) Polar coordinate system (a.k.a. Circular coordinate system), (ii) Elliptic coordinate system.

Step-by-step explanation:

There are two alternative ways of describing the location of points on a plane:

(i) Polar coordinate system (a.k.a. Circular coordinate system).

(ii) Elliptic coordinate system.

Now we proceed to explain briefly the characteristic of each option:

Polar coordinate system:

Where:

- Distance of the point with respect to origin.

- Direction of the vector between origin and point with respect to the +x semiaxis, in sexagesimal degrees.

The formulae for each component in terms of Cartesian coordinates are described below:

(1)

(2)

Elliptic coordinate system:

Where and are elliptical coordinates.

The formulae for each component in terms of Cartesian coordinates are described below:

(3)

(4)

Where is the distance between origin and any of the foci along the x axis.
