If `|z|=1` and `z'=(1+z^(2))/(z)`, then

If |2z-1|=|z-2| and z_(1),z_(2),z_(3) are complex numbers such that |z_(1)-alpha| |z|d.>2|z|

If |z_(1)| = |z_(2)| = 1, z_(1)z_(2) ne -1 and z = (z_(1) + z_(2))/(1+z_(1)z_(2)) then

If |z_(1)+ z_(2)|=|z_(1)|+|z_(2)| , then arg z_(1) - arg z_(2) is

If | z_ (1) + z_ (2) | = | z_ (1) -z_ (2) |, then arg z_ (1) -arg z_ (2) =

If z_(1),z_(2) are two complex numbers satisfying the equation : |(z_(1)-z_(2))/(z_(1)+z_(2))|=1 , then (z_(1))/(z_(2)) is a number which is

If Z_(1)=1+i and Z_(2)=2+2i , then which of the following is not true. (A) |z_(1)z_(2)|=|z_(1)||z_(2)| (B) |z_(1)+z_(2)|=|z_(1)|+|z_(2)| (C) |z_(1)-z_(2)|=|z_(1)|-|z_(2)| (D) |(z_(1))/(z_(2))|=(|z_(1)|)/(|z_(2)|)

If z_(1)!=z_(2)o*|z_(1)+z_(2)|=|(1)/(z_(1))+(1)/(z_(2))|, then (Z_(1),Z_(2)in C)?

If z_(1) and z_(2), are two complex numbers such that |z_(1)|=|z_(2)|+|z_(1)-z_(2)|,|z_(1)|>|z_(2)|, then
