What is the coordinate of a point on a circle from a different perspective?

In summary, the conversation discusses the coordinates of a point on a circle with its center at (h,k) and radius R, and how it differs when viewed from the perspective of (h,k) or (x,y). The code written in Delphi provides the answer to this query and also mentions solving a bug in an Astrology program. One person expresses surprise and disapproval at the idea of an Astrology program.

I've a small Query.
Suppose a circle is plotted with its center at distance h,k (from x=0, y=0) with radius R. If theta is an angle from h,k to any point over the circle, we know that the co-ordinate of that point, from (h,k) perspective, will be Rcos(theta),Rsin(theta). In such a case, what shall be the co-ordinate of the SAME POINT, if it is taken from x,y.

Well naturally it would be ( h + R cos(theta), k + R sin(theta) ).
