If `|z-25i|leq 15`, then value of `max (arg(z))` is

If |z- 25i| le 15 , then |maximum arg (z) - minimum arg (z)| equals

If 'z, lies on the circle |z-2i|=2sqrt2 , then the value of arg((z-2)/(z+2)) is the equal to

If 'z, lies on the circle |z-2i|=2sqrt2 , then the value of arg((z-2)/(z+2)) is the equal to

If 'z, lies on the circle |z-2i|=2sqrt2 , then the value of arg((z-2)/(z+2)) is the equal to

If 'z, lies on the circle |z-2i|=2sqrt2 , then the value of arg((z-2)/(z+2)) is the equal to

Write the value of arg(z)+arg(bar(z))

If |z-25i|le15 , then |maximum arg(z) - minimum arg(z)| equals (A) (pi)/(2)+cos^(-1)((3)/(5)) (B) sin^(-1)((3)/(5))-cos^(-1)((3)/(5)) (C) 2cos^(-1)((4)/(5)) (D) 2cos^(-1)((1)/(5))

If z= frac{-2}{1+sqrt3i} , then the value of arg(z) is

If z =(-2)/(1+sqrt3i), then the value of arg(z) is-

If |z-25i| lt= 15. then |"maximum " arg(z) - "minimum " arg(z)| equals
