Find the gratest and the least values of `|z_(1)+z_(2)|,`
if `z_(1)=24+7iand |z_(2)|=6," where "i=sqrt(-1)`

Find the argument s of z_(1)=5+5i,z_(2)=-4+4i,z_(3)=-3-3i and z_(4)=2-2i, where i=sqrt(-1).

If |z|ge3, then determine the least value of |z+(1)/(z)| .

1. If |z-2+i| ≤ 2 then find the greatest and least value of | z|

The equation z^(2)-i|z-1|^(2)=0, where i=sqrt(-1), has.

If |z|=1 and z!=1, then all the values of z/(1-z^2) lie on

If the points represented by complex numbers z_(1)=a+ib, z_(2)=c+id " and " z_(1)-z_(2) are collinear, where i=sqrt(-1) , then

Consider four complex numbers z_(1)=2+2i, , z_(2)=2-2i,z_(3)=-2-2iandz_(4)=-2+2i),where i=sqrt(-1), Statement - 1 z_(1),z_(2),z_(3)andz_(4) constitute the vertices of a square on the complex plane because Statement - 2 The non-zero complex numbers z,barz, -z,-barz always constitute the vertices of a square.

Find the maximum and minimum values of |z| satisfying |z+(1)/(z)|=2

If |z_(1)|=|z_(2)|andamp(z_(1))+amp(z_(2))=0, then

The points A,B and C represent the complex numbers z_(1),z_(2),(1-i)z_(1)+iz_(2) respectively, on the complex plane (where, i=sqrt(-1) ). The /_\ABC , is a. isosceles but not right angled b. right angled but not isosceles c. isosceles and right angled d. None of the above
