<p>formally backing up nilkn.</p>
<p>de Moivre’s formula
(cos(x) + i<em>sin(x))^n = cos(nx) + i</em>sin(nx)</p>
<p>mode: degrees
z = cos(30) + i<em>sin(30)
z^n = cos(30n) + i</em>sin(30n)
z^n = 1
cos(30n)=1 and sin(30n)=0
30n = 360k, where k is any integer
n = 12k
for k=1 n=12.</p>

<p>if this question showed up on ACT, i’d be 0_0. where do you get your questions? how many people asking you will it take to have you divulge your collegiate confidential sources?
