There are four ways to represent a complex number and its complex conjugate.

A complex number can also be written as

(Ordered Pair Form)

(Cartesian Form)

(Trigonometric Form)

(Polar Form)

All above four forms are representing the same complex number.

A complex conjugate can also be written as

(Ordered Pair Form)

(Cartesian Form)

(Trigonometric Form)

(Polar Form)

All above four forms are representing the same complex conjugate number.

It follows that
