If `arg""(z-1)/(z+1)=(pi)/(4),` show that the locus of z in the complex plane is a circle.

If arg((z-1)/(z+1))=(pi)/(2) then the locus of z is

If arg((z-2)/(z+2))=(pi)/(4) then the locus of z is

If the real part of (z +2)/(z -1) is 4, then show that the locus of he point representing z in the complex plane is a circle.

If the real part of (z+2)/(z-1) is 4, then show that the locus of he point representing z in the complex plane is a circle.

If the real part of frac{bar z + 2}{bar z -1} is 4, then show that the locus of the point representing z in the complex plane is a circle.

If arg ((z-1)/(z+1))=pi/4 ,, then show that in complex plane, the locus of z is a cricle.

If the real part of (barz + 2)/(barz - 1) is 4, then show that locus of the point representing z in the complex plane is a circle.

If Arg ((z+1)/(z-1))=pi/6 then the locus of z = x + iy is
