What did you use to go from -1/2(cosec theta +cot theta) to the final answer please? Checked the formula book but couldn't see anything in there, thanks!
5. How is 8d done tried it but can't remember anything from previous core mods please?

Look where it says integral of cosec, you use the log laws to raise the powers and deduce that cosec plus cot is 1/ tan(1/2x)

Can you look at my post above for help please?
8. How is first q done. The induction one? I tried writing it in a form of differentials but went awkward.

Preferably a written solutions with pictures please

And the induction q if u can

I've found the radius, but stuck on how to find the y-coord of the centre!

That's exactly where I am dude.

It's probs a circle theorem of some kind but can't think what, will ask my teacher on monday and post his working
14. Struggling with this.
First 2 pics shows approach 1 and 3rd is second approach

With 4th pic showing q which is 9b

Assume true for n=k and then differentiate once more and algebra manipulate to show that it's true for n=k+1. If you're stuck then post your solution.

Wait what did you get for radius? How'd you get it

2root3, used 2 of the points I already knew with the C2 distance formula on (7,4) and (4, 4+root3) then did (x-x1) squared + (y-y1 squared) with those two coords

Ya I got 2root 3 but for distance between 7,4 and 4,4+root3 but why is that length the same?
This is the logic I put together as to why the centre is what it is but I don't get why distance are the same and hence both are root3 downwards from 4,4 +root3

EDIT: I don't know why but the bottom triangle might be the same as top
which is why they got what they got but could be wrong.

SEE 2 posts below for second pic.

I have not attempted this question yet, but here are my initial thoughts. If this doesn't help then I'll take a look at it tomorrow morning.

Your second attempt is the right approach.

You need your argument to just be in one plane, the w-plane. Make z the subject of the transformation, and add 2i to both sides of the transformation to achieve the expression you desire
