If `Re((z-1)/(2z+i))=1,` where `z=x+iy` ,then the point `(x,y)` lies on a

If |(z +4)/(2z -1)|=1, where z =x +iy. Then the point (x,y) lies on a:

If |z|+2=I(z), then z=(x,y) lies on

If Re((z-1)/(z+1))=0 where z=x+iy is a complex number,then which one of the following is correct? (a) z=1+i(b)|z|=2 (c) z=1-i

If (pi)/(8)+i beta=cot^(-1)(z) where z=x+iy then the locus of z is

Consider a complex number w=(z-1)/(2z+1) where z=x+iy, where x,y in R . If the complex number w is purely imaginary then locus of z is

Let a,b in R and a^2+ b^2 ne 0 Suppose S={z in C : z =(1)/(alpha +I bt ), t in R, t ne 0 } where I= sqrt(-1) if z=x +iy and ne S, then (x,y) lies on

Let a,b in R and a^(2) + b^(2) ne 0 . Suppose S = { z in C: z = (1)/(a+ ibt),t in R, t ne 0} , where i= sqrt(-1) . If z = x + iy and z in S, then (x,y) lies on
