(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

given |z|=3, Arg(z)=5Pi/6

find a+ib form of the complex number.

2. Relevant equations

3. The attempt at a solution

so from the arg(z) we can say it lies in the second quad.

Since 5Pi/6 is equivalent to then 180-150 =30

so,

3(sqrt3/2 +1/2i)

but they had 3/2(-sqrt3+i)

why is it negative? since 150 is in the sec quad.
