First find out the radius of the circle given:
x^2 + y^2 – 2x = 0 .
And assume locus of center be P(a,b)
and T be touching point and And foot of a perpendicular line from P to H.
then by geomtery the relation would come out as:
PC – 2 = a = PH = PT
where C is the centre for the given circle.
Now U can do further easilyy.
Try it.
put PC magnitude.
