Is there a specific but that you don't understand about the markscheme? Have you looked at examsolutions.net videos on complex transformations?

Yeah, I understand how you get to the fraction representing w but I don't really understand how you'd know to go from here to finding the modulus of the numerator and denominator as I've not seen this method used before? Yeah I have, but I'm still struggling with bits of them quite a lot :/ Thanks
5. Can someone please help me with this step? I don't understand where the (pie/3 - theta ) goes

btw it is from Jan05 p4 Q7
Thanksbtw it

thanks , I do understand this (this was part a of the question )

if possible could you explain the step I attached earlier

edit:the image is part of the mark scheme and is not a question I just don't understand how they got there

Sure, is it part c you'd like a worked solution to?

It's probably obvious but on the MS how do you know that the square root of lambda+1 squared plus lambda squared is 1? Thanks

It's not saying the square root of the thingies squared is 1. It's saying that

So that

i.e: the modulus of the numerator is the same as the modulus of the denominator. Hence the modulus of the entire thing is just 1.

No worries.
20. For de moivre's theorem, do we need to know the proof for both positive and negative integers? I mean positive i can manage it's just proof by induction by negative is just like extraaa...
