(a,c) and (b,c) are the centres of two circles whose radical axis is the y-axis.If the radius of the first circle is r then the diameter of the other circle is

(iv) The position of the radical axis of the two circles geometrically is as:

The equation of the radical axis of the system of coaxial circles x^2 + y^2 + 2ax + 2by + c + 2lambda(ax-by + 1) = 0 is

Point O is the centre of a circle . Line a and line b are parallel tangents to the circle at P and Q. Prove that segment PQ is a diameter of the circle.

Fill in the blanks (i) A line intersecting a circle in two distinct points is caled a…. (ii) A circle can have… parallel tangents at the most. (iii) The common point of a tangent to a circle and the circle is called the…. (iv) A circle can have.... tangents.

Find the equation of the system of circles co-axial with the circles x^(2)+y^(2)+4x+2y+1=0andx^(2)+y^(2)-2x+6y-6=0 Also, find the equation of that particular circle whose cneter lies on the radical axis.
