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

If z lies on unit circle with center at the origin, then (1+z)/(1+barz) is equal to

If z lies on unit circle with center at the origin, then (1+z)/(1+barz) is equal to

If z = 3 + i , then (z+1)(barz+1)=

Let z_1 and z_2 are two complex nos s.t. abs(z_1) =abs(z_2)=1 then abs((z_1-z_2)/(1-z_1 barz_2)) is equal to

If z is a non zero complex, number then |(|barz |^2)/(z barz )| is equal to (a). |(barz )/z| (b). |z| (c). |barz| (d). none of these

If z is a complex number of unit modulus and argument theta , then arg((1+z)/(1+barz)) equals

P(z) be a variable point in the Argand plane such that |z|=minimum {|z?1, |z+1|} , then z+barz will be equal to a. -1 or 1 b. 1 but not equal to-1 c. -1 but not equal to 1 d. none of these

P(z) be a variable point in the Argand plane such that |z| =minimum {|z−1, |z+1|} , then z+barz will be equal to a. -1 or 1 b. 1 but not equal to-1 c. -1 but not equal to 1 d. none of these

P(z) be a variable point in the Argand plane such that |z| =minimum {|z−1|, |z+1|} , then z+barz will be equal to a. -1 or 1 b. 1 but not equal to-1 c. -1 but not equal to 1 d. none of these
