If `|z|=1a n dz!=+-1,` then all the values of `z/(1-z^2)` lie on (a)a line not passing through the origin (b)`|z|=sqrt(2)` (c)the x-axis (d) the y-axis

Equation of line passing through z1and z2

Find the equation of plane containing the line x+y-z=0=2x-y+z and passing through the point (1,2,1)

If |z_(1)|=|z_(2)|=………….=|z-(n)|=1 , then the value of |z_(1)+z_(2)+………+z_(n)| , is

If z!=1 and (z^2)/(z-1) is real, then the point represented by the complex number z lies (1) either on the real axis or on a circle passing through the origin (2) on a circle with centre at the origin (3) either on the real axis or on a circle not passing through the origin (4) on the imaginary axis

If |z^(2)-1|=|z|^(2)+1, then z lies on (a) a circle (b) the imaginary axis (c) the real axis (d) an ellipse

If |z^(2)-1|=|z|^(2)+1, then z lies on (a) a circle (b) the imaginary axis (c) the real axis (d) an ellipse

If |z^(2)-1|=|z|^(2)+1, then z lies on (a) a circle (b) the imaginary axis (c) the real axis (d) an ellipse

If |z^(2)-1|=|z|^(2)+1, then z lies on (a) a circle (b) the imaginary axis (c) the real axis (d) an ellipse

Equations of the line passing through (a,b,c) and parallel to Z - axis , are
