ooffff what time do you sleep and wake up I feel like I'm the only one with a horrid sleeping schedule
On school days I'd sleep at 12 and wake up 7-7:30 cuz school's of a good walking distance from home, but in holis I sleep 1/2ish sometimes 3

I'd love to wake up at 6:30 on school days and get some exercise before school but thing is I've tried that, I've set an alarm for 6:30, it rings and my body's like no bueno so I end up sleeping in more

My entire high school life I’ve been sleeping pretty early (6-9pm) and waking up around 4am, now ever since fucking prelims I’ve completely ruined my perfect sleep pattern and I’m very sad
Damn that sucks! How did your sleep schedule get ruined

Saw a video after on a similar question to this and I regret it so much for not watching it as my understanding of roots of unity was crap at the time I was taking this exam ~ teacher didn't explain it too well.

Ye I was given the step to differentiate, but I for some reason forgot at the time about double roots and stuff so I wasted time trying to find sum and product of roots and didn't even end up getting the full question
For part C if you want a truly quick solution,
-sub in 'i' into the RHS of (b), you get product of roots as z^2 and 1 cancel out, do this to the sum of roots on LHS.
-sub in '1' into RHS of (b), expand the brackets and u get sum of roots, do this to the sum of roots on LHS.
