यदि `|z^(2)-1|=|z|^2+1`, तब z स्थित है:

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

Let z_(1), z_(2), z_(3) be three complex numbers such that |z_(1)| = |z_(2)| = |z_(3)| = 1 and z = (z_(1) + z_(2) + z_(3))((1)/(z_(1))+(1)/(z_(2))+(1)/(z_(3))) , then |z| cannot exceed

If x+y+z = 400 and x:y:z = 1:1:2. Then find the value of z ? यदि x+y+z = 400 तथा x:y:z = 1:1:2 है, तो z का मान ज्ञात करें ।

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 two complex numbers z_(1) and z_(2) are such that |z_(1)|=|z_(2)| , is it then necessary that z_(1)=z_(2) ?
