Conjugation of a complex number describes an axial symmetry of the complex plane. To conjugate a complex number, reflect its position through the real axis. This geometric significance is used a lot; e.g., http://www.amazon.com/Abels-Theorem-Problems-Solutions-International/dp/1402021860

Answer 2

@Samie509 did u get it

Answer 3

Not quite but im getting there # thank you :)

Answer 4

when a complex number is multiplied by its
complex conjugate you get the numbers measure or modulus

\[\left|a+ib\right|=\sqrt{(a+ib)\overline{(a+ib)}}=\sqrt{(a+ib)(a-ib)}=\sqrt{a^2+b^2}\]

Answer 5

Thank yOu wt is its usefullness tho :)
