Hi all, as Drsoccerball requested i'll just post the questions on here from now on, these are all pretty hard. Could I also get some help with Q10 from the polynomial set? Is it similar logic to Q3?

Q3 from ekman's polynomial set? It is stickied to the ext 2 thread - neither I nor my teacher understands how to crack it.

Thanks for the feedback everyone - hopefully I can maintain this form throughout the year...

Currently working through Terry Lee's text, I noticed the worked solutions provided a swift workaround for using De Moivre's theorem, having ASSUMED that it is true for all rational numbers. As far as I have seen from the ext 2 course, De Moivre's theorem is only proved for the integer set...

This is question 19 from 9I Cambridge Maths Year 11 extension 1 text. P is a variable point on the parabola x^2 = 4y. The normal at P meets the parabola again at Q. The tangents at P and Q meet at T. S is the focus and QS = 2PS. i) Prove that angle PSQ = 90 degrees ii) prove PQ=PT I...

Hi everyone, I'm currently in the class of 2016 but am pretty keen on doing actuarial studies/maths in university. Maths is by far my favourite and best performing subject, and would like to continue that through for later years. Basically at the moment I know the UNSW course is quite good...

I'd say for Chapter 4 and 5 especially, revise up on the multiple choice stuff as well - particularly balance of payments categories. With 30 marks multiple choice, knowing your categories back to front can help not only maximise marks but also maximise time to focus on rest of the test. A...

I've got all four of the main ones; Creative economics by Moore, Australia in the Global Economy by Dixon, Year 12 economics by Riley and Updated Economics 2016 by John Bulmer. All are great for their own reasons, but essentially I've gotten most of my elementary understanding from Moore and...

Our school is going by the book so far... Apart from Topic 2 in which some texts/schools choose to cover exchange rates before moving into Balance of Payments. I find starting with Topic 3 a bit strange, considering a lot of the content is sort of tied into previous topics and the preliminary...
