18`S, 175`E by the usual measure, or -18.00, 175.00 in polar.
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

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).
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.
In polar coordinates, the curl of a vector field represents how much the field is rotating around a point. The relationship between the curl and the representation in polar coordinates is that the curl can be calculated using the polar coordinate system to determine the rotational behavior of the vector field.
