The largest value of r for which the region represented by the set
is contained in the region represented by the set is equal to:
As we have learned
Perpendicular bisector -
Locus of point equidistant from two given points.
z will lie on perpendicular bisector of line joining and .
- wherein
and are any two fixed points . z is a moving point in the plain which is equidistant from and .so z will lie on perpendicular bisector
Equation of circle -
= centre of circle
r= radius of circle
z lies on circle.
- wherein
Locus of z will be a circle as z is always at a fixed distance r from a fixed point
