Find all complex numbers z for which (z-2)/(z+2) is purely imaginary.

Let z!=i be any complex number such that (z-i)/(z+i) is a purely imaginary number. Then z+ 1/z is

Let z!=i be any complex number such that (z-i)/(z+i) is a purely imaginary number.Then z+(1)/(z) is

Write the real and imaginary parts of the complex number: 2-i sqrt(2)

Write the real and imaginary parts of the complex number: 2-i sqrt(2)

Write the real and imaginary parts of the complex number: - (1/5+i)/i

If z is a unimodular number (!=+-i) then (z+i)/(z-i) is (A) purely real (B) purely imaginary (C) an imaginary number which is not purely imaginary (D) both purely real and purely imaginary
