" If "z=x+iy," then the centre of the circle "|(z-3)/(z-2i)|=2" is "

Find the radius and centre of the circle z bar(z)- (2 + 3i) z-(2-3i) bar(z)+ 9=0 where z is a complex variable

Find the radius and centre of the circle z bar(z) - (2 + 3i)z - (2 - 3i)bar(z) + 9 = 0 where z is a complex number

If z=x+iy, then the equation |(2z-i)/(z+1)|=k will be a straight line,where -

If z=x+iy, then 1<=|z|<=3 represents

If z = x + iy such that cos z = 2, then z =

If |z-3+i| = 4 then the locus of z = x +iy is

If z=x+iy, then he equation |(2z-i)/(z+1)|=m represents a circle,then m can be (1)/(2) b.1 c.2d.3

The locus of z=x+iy satisfying |(z-i)/(z+i)|=2

If z= x+iy find the locus of z if |2z+1| = 2 .
