hey

i havent studied in class complex numbers yet, but i know some of the basis , and i was wondering if something i saw in complex numbers was true :

polar form :

let 'a' be the angle

and x the length (dont know how to call it in english)

: (x, a)

ok so now is this true :

-> ( (x, a) )^n = (x^n, a * n)

-> sqroot( (x, a) ) = (sqroot(x), a/2) or (sqroot(x), pi + a/2)
