    A complex number z is defined to be

    z = x + iy,

    where x and y are real numbers, and i=\sqrt{-1}. x is the REAL part of z and y is the IMAGINARY part of z.

    Notice that z = i\sqrt{2} = 0 + i\sqrt{2}.

    What are the real and imaginary parts of z?

    If z = x + iy then Re(z) = x and Im(z) = y.

    Yuo have z = 0 + i \sqrt{2} \, ....
