Nah Namu, the question is right... prior to 4 unit maths, it is known that if the discriminant is negative, the roots are unreal (whatever that may mean) - but it still means there are roots

from there make b = pi - a sub b into cos(b/2) = 2cos(a/2) you'll end up getting a = 2 x inversetan2 then b = pi - 2 x inversetan 2 z1 = cis a z2 = cis b just type it into the calculator and yeah...

okay i did this thinking, no way in hell I'll get this cause I haven't done complex numberes in ages but my answers look believable so if right, I'll post up my answer.. z1 = -3/5 + 4i/5 z2 = 3/5 + 4i/5
