If `z_1=a+ib` and `z_2=c+id` are two complex numbers then `z_1 gt z_2` is meaningful if

Read the following writeup carefully: If z_1 = a+ib and z_2 =c + id be two complex numbers such that |z_1| = |z_2|=1 and "Re" (z_1 bar(z_2))=0 . Now answer the following question Let k = |z_1 + z_2| + |a+ ib| , then the value of k is

Read the following writeup carefully: If z_1 = a+ib and z_2 =c + id be two complex numbers such that |z_1| = |z_2|=1 and "Re" (z_1 bar(z_2))=0 . Now answer the following question If a , b gt 0 and c lt 0 , then

Read the following writeup carefully: If z_1 = a+ib and z_2 =c + id be two complex numbers such that |z_1| = |z_2|=1 and "Re" (z_1 bar(z_2))=0 . Now answer the following question Let W = a+ic , then the locus of |(W+1)/(W-1)|=1 is (where W ne 1 )

Let z_(1)=a+ib and z_(2)=c+id are two complex number such that |z_(1)|=|z_(2)|=r and Re(z_(1)z_(2))=0 .If w_(1)=a+ic and w_(2)=b+id, then (a) |w_(1)|=r( b) |w_(2)|=r (c) Re(w_(1)w_(2))=0 (d) Im(w_(1)w_(2))=0

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

If z_(1) = a + ib " and " z_(2) + c id are complex numbers such that |z_(1)| = |z_(2)| = 1 and Re (z_(1)bar (z)_(2)) = 0 , then the pair of complex numbers w_(1) = a + ic " and " w_(2) = b id satisfies :
