Let `z_1 and z_2`q, be two complex numbers with `alpha and beta` as their principal arguments such that `alpha+beta` then principal `arg(z_1z_2)` is given by:

Let z_1 and z_2 , be two complex numbers with alpha and beta as their principal arguments such that alpha+beta gt pi then principal arg(z_1z_2) is given by:

z_(1) and z_(2) be two complex numbers with alpha and beta as their principal arguments, such that alpha + beta gt pi , then principal Arg (z_(1) z_(2)) is

Let z_(1) and z_(2)q ,be two complex numbers with alpha and beta as their principal arguments suith that alpha+beta then principal arguments suiven by:

Let z be any complex number such that the principal value of argument , arg(z)-arg(-z) is

Let z be a complex number such that the principal value of argument, argzgt0 . Then argz-arg(-z) is

A complex number is given by z=(1+2i)/(1-(1-i)^(2)) What is the principal argument of z?

Let z_1 and z_2 be two distinct complex numbers and let z= (1-t)z_1+tz_2 for some real number t with 0lttlt1 . If Arg(w) denotes the principal argument of a non-zero complex number w, then
