*** the conjugate of a complex number with −1 as the real part and 3 as the imaginary part? ***

given  -1+3i
the complex conjugate means negate the imaginary part
so
-1 -3i  is the complex conjugate of -1+3i  (and vice versa)

right, phi is right, I forgot that the imaginary part comes second > >
