Find the equation of the ellipse whose foci are at the points S(2, 0) and S^(') (-2, 0), and whose latus rectum is 6.

If a circle cuts orthogonally three circles, S_1 = 0, S_2=0, S_3=0 , prove that it cuts orthogonally and circle kS_1 + lS_2 + mS_3 = 0 .

Let S_(1)=0 and S_(2)=0 be two circles intersecting at P(6,4) and both are tangent to x -axis and line y=mx( where m>0). If product of radii of the circles S_(1)=0 and S_(2)=0 is (52)/(3) then find the value of m.
