thank you for your help, however i have arrived at the result by unsing coordinate geometry by letting the the centre of fixed circle of radius r be the origin, (a,0) be the fixed point and extremetries of diameter (rcos(theta)), rsin(theta)) and (rcos(theta0,rsin(theta))and the centre of variable cicle has a fixed x cordinate
i also consulted help from another maths forum, and i find the proof very nice,thus it is worth a look:http://www.mathlinks.ro/viewtopic.php?t=200331
