z = x + i y
Re(1/z) = x/(x^2+y^2) = k
so k x^2 - x + k y ^2 = 0
(x - 1/2k)^2 + y^2 = 1/ 4k^2
This is a circle with radius 1/2k and center (1/2k, 0).

Answer:
(1/2k, 0)
Step-by-step explanation:
Given,
Re(1/z)=k where k is non zero real number.
To Find,
The locus of point z.
z = x + i y
Re(1/z) = x/(x^2+y^2) = k
so k x^2 - x + k y ^2 = 0
(x - 1/2k)^2 + y^2 = 1/ 4k^2
This is a circle with radius 1/2k and center (1/2k, 0).
