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

[ad_bose]

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.

Kindly see Attached code written in Delphi.

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