If a r g(z)<0, then a r g(-z)-"arg"(z) equals pi (b) -pi (d) -pi/2 (d) pi/2

If arg (z)<0, then underset(pi)/(2)arg(-z)-arg(z) equals pi(b)-pi(d)-(pi)/(2)(d)(pi)/(2)

If arg z = pi/4 ,then

If -pi

Show that arg. bar z =2 pi- arg. z .

If Argzlt0 then (Arg(-z)-Arg(z))/(pi(cos(pi/3)) is equal to

If z_(1) and z_(2), are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_(1)|+|z_(2)| then arg(z_(1))-arg(z_(2)) is equal to (1)0(2)-(pi)/(2) (3) (pi)/(2)(4)-pi

If z_1 and z_2 be complex numbers such that z_1 + i(bar(z_2) ) =0 and "arg" (bar(z_1) z_2 ) = (pi)/(3) . Then "arg"(bar(z_1)) is equal to a) (pi)/(3) b) pi c) (pi)/(2) d) (5pi)/(12)
