absolute relative and polar coordinates definition
If the polar coordinates of a point P are (r,a) then the rectangular coordinates of P are x = rcos(a) and y = rsin(a).
You don't!
That is because - for example - some calculations are easier in polar coordinates, and some are easier in rectangular coordinates. For example, complex numbers are easier to add and subtract in rectangular coordinates, and easier to multiply and divide in polar coordinates.
The abscissa in Cartesian coordinates. In polar coordinates, it would be the radius .or domain

The point whose Cartesian coordinates are (2, 0) has the polar coordinates R = 2, Θ = 0 .
The point whose Cartesian coordinates are (-3, -3) has the polar coordinates R = 3 sqrt(2), Θ = -0.75pi.

Some problems are easier to solve using polar coordinates, others using Cartesian coordinates.

Polar coordinates are another way to write down a location on a two dimensional plane. The first number in a pair of coordinates is the distance one has to travel. The second number in the pair is the angle from the origin.
