If `|z| < sqrt(2)-1` then `|z^2+2z cos alpha|` is.

If |z_1|=|z_2|=|z_3|"…."=|z_n|=1 then |z_(1)+z_(2)+"….."+z_(n)|=

If |z_1|=|z_2|=|z_3|=1 then value of |z_1-z_3|^2+|z_3-z_1|^2+|z_1-z_2|^2 cannot exceed

If |z-3|=min{|z-1|,|z-5|} , then Re(z) equals to

If |z-1|=|z-3| then the locus of z is

If | z - (3)/(z) | = 2, then the least value of |z| is

If |z-i R e(z)|=|z-I m(z)| , then prove that z , lies on the bisectors of the quadrants.

If z_1, z_2, z_3, z_4 are the affixes of four point in the Argand plane, z is the affix of a point such that |z-z_1|=|z-z_2|=|z-z_3|=|z-z_4| , then z_1, z_2, z_3, z_4 are

If |z-z_(1)|=|z-z_(2)| then the locus of z is :
