" 65.If: "|Z|=1," then ":(1+Z)/(1+bar(Z))=

Select and write the correct answer from the given alternatives in each of the following: If |z| = 1, then (1 + z) /(1 + bar z) is equal to

If |z|=1, then (1+z)/(1+bar(z)) is equal to

If z=i-1, then bar(z)=

If |z| = 1, then the value of (1+z)/(1 +bar(z)) .

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

If |z_(1)|!=1,|(z_(1)-z_(2))/(1-bar(z)_(1)z_(2))|=1, then
