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

If the imaginary part of (2z+1)/(iz+1) is -2, then find the locus of the point representing in the complex plane.

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

If Re((2z+1)/(iz+1))=1 , the the locus of the point representing z in the complex plane is a (A) straight line (B) circle (C) parabola (D) none of these

The centre of circle represented by |z+1|=2|z-1| in the complex plane is

Find the complex number z if z^2+barz =0

If (1+i)z = (1-i)barz, "then show that "z = -ibarz.
