Complex numbers - polar form - does this work (indices) ?
hey
i haven't 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)
