8 It is given that \(m = - 4 + 2 \mathrm { j }\).
- Express \(\frac { 1 } { m }\) in the form \(a + b \mathrm { j }\).
- Express \(m\) in modulus-argument form.
- Represent the following loci on separate Argand diagrams.
(A) \(\arg ( z - m ) = \frac { \pi } { 4 }\)
(B) \(0 < \arg ( z - m ) < \frac { \pi } { 4 }\)
